I personally would say take your time gathering the supplies as you have the money then. Here's a bit of the back story for when I started my journey into this part of the reptile hobby. Like you, I had been interested in chams for a long time. I had mainly kept snakes previously as well. So here's the story, it'll be a long post so I apologize for that but hopefully you'll understand why I say take your time then get the cham in this case....
I was in one of the only two dedicated reptile shops in my area that I know of and saw a male veiled that my wife and I fell in love with. I want to say this was late August. I spent the rest of late August and Sept doing my research here and finally piped up on
@Traildrifterphalanx thread I want to say late Sept. His thread at first had me really second guessing myself on getting into chams beyond looking at them in pet shops. Then as I read on it got better and his story prompted me to say something along the lines of it gave me hope we could have success with keeping chams too. I had mentioned the little male veiled I had seen and was directed to
@Matt Vanilla Gorilla since pet shop chams can be questionable at times but I had already sent someone a txt on their chams so I didn't immediately reach out to him.
I had sent the other person a txt about a listing for cape est they had for sale on 10-1 looking to see what their prices were and how many they may have had available. I did this for two reasons, one I wanted to know what I was looking at price wise going through a breeder and my original plan was to take the month of Oct to build out an enclosure buying a little bit each week. As soon as I mentioned the part of wanting to setup the enclosure over the month of Oct all communication stopped with this person. I understand breeders are extremely busy but as a possible customer this really irked me to no end. I felt that even though I may not buy what he had at that very moment a rough idea on pricing since there was no published prices wouldn't have been that hard to say and then when I was ready I could've asked if he still had any or, make a deal like I ended up doing with Matt.
My wife and I took the next few days to see if he would respond to my last txt and he never did so I sent Matt a message on 10-4 asking about his pricing and availability and I can honestly say, I'm beyond glad we did. He replied with his phone number and to txt him but I had already gone to bed for the night. We spent most of the next day talking about my plans, his availability and he sent me pics of the only two he had left at the time. My beloved Blue Lighting and one of his sisters. Though I had told him the same thing that I was looking to take the month to get setup, Matt patiently stuck with me as we talked in between both of us being at work. I loved how Blue looked at first sight, kind of like that butterfly feeling you get when you think you've found the right girl for yourself

, and his sister. My wife and I had discussed the possibility of trying to breed down the road so I had talked with Matt about this too while I waited to meet up with my wife later that night to get her thoughts on Blue. Both Matt and I were in a holding pattern for probably 3 or 4 hours at that point. Blue was one of Matt's hold backs so he wanted to get his wife's thoughts on price and I needed to get my wife's thoughts on him but we still chatted about various things in the mean time.
My wife absolutely loved him when she saw his pics. To the point of her not even questioning what price he was it was a "OMG, I have to have him". Matt told me what they were looking to get out of him and I mulled it over with my wife on seeing if Matt would let us make the purchase but hold him until we were ready. We both wanted him to be our first cham there was no doubt about it but we were far from prepared to actually buy him at that point. So I "countered" Matt on a deal that I thought would help us secure Blue as our first cham, still give us the month to get setup as properly as we could and help cover the added costs for Matt if he agreed. Needless to say we agreed on a deal and over the next month I built out Blue's enclosure as my time and weather permitted. During this month I ran my ideas by Matt and he would give his input on if he thought it would work or not. Many things changed as I went along, MANY! We talked so much during this month he became more of a mentor and brother from another mother then just the guy I was buying my first cham from lol. We still talk at least every other day if not every day about things I may have a question about or just life in general. But, all this said, even though we made our first cham purchase before we were really prepared for doing so, we still wanted to make sure we were as prepared for him to arrive as we could be before him coming to his new home. I really feel it is the best way to go for both yourself and the cham you end up getting. If you haven't already, read through
@Traildrifterphalanx thread on getting his first cham. It is a long read but well worth the read.
Trust me I know the feeling of wanting to have one now lol. It was almost torturous for us during that month of building knowing Blue was across the country waiting to come here. During that month our air handler decided to put a wrench in our plans which threatened to put me back a weeks build time and a weeks supply money. Matt was very understanding about the situation though. In the end we ended up pulling some from our savings to finish the build out because my wife decided she didn't want to wait the extra week for him to arrive

. Matt was kind enough to send us pic updates and videos though which was awesome of him to do. But, I would do it the same way now if I had to do it all over again as I did then. Sorry for having been so long winded but hopefully it helps with understanding my view point. As mentioned before, take your time and set it up the right way the first time
