You could, but why?
To ease your fears, perhaps you can start off slowly at your own pace by getting the cage all set up first, including the measuring instruments, supplements, branches, plants, lighting, etc. Then start a thread and post pictures of your set up and everything that you have ready to go except for the feeders and the cham. You will get great feedback here and then you will feel more confident about being ready for this. Then a day or two (or more if mail ordering) when the cham is expected to arrive, you have the feeders ready for the cham's arrival.
All of that stuff it pretty easy to maintain. For heat all you need is the right bulb, misting you can get an automatic one to take care of it. For humidity, the mister will help, live plants help a lot to, and if your still having problems you can get a cheap humidifier from a place like walmart and put it somewhere near the cage. I myself have all three. If your getting a veiled all you need is between 50 and 70 percent.
Most of it comes from them not doing something right and then not wanting to fix the problem. Some times they don't like what people have to say, like when they are constantly handling a cham that doesn't want to be handled and the animal gets sick because of it, that person doesn't believe that their constant handling could be the problem.
Thats really the biggest thing to worry about. If you choose a bad breeder and you get an unhealthy animal then it really complicates things. Since you have found a good one you don't have to worry that much because you know you will be getting a healthy high quality animal.
