Welcome back.

Just have to ask how your beardie is doing. They are often said to be good for beginner reptile keepers, but from my own experience, they are just as expensive and as much (or even more) work than chameleons.
Rather than list everything, the best way to get the basics is Neptune’s kit.

I’m not sure what part of Texas they are in, but

I’m not at all familiar with the places you name, but do keep in mind that these is a huge amount of misinformation about husbandry out there. The most accurate source is

@IrohtheVeiled is correct that chameleons can be expensive to care for. There are some ways to reduce some costs, such as breeding your own feeder insects, using natural branches instead of bought vines. It is always a good idea to have a bit of $$ set aside for any unexpected or emergency vet visits. Most important for someone your age though is having the full support emotionally, physically and financially of a parent. You’ve been very patient and waited, so make sure now to set yourself up for success.
