Hi there and welcome. Here is the link to the Chameleon Breeder Podcast that Bill Strand does. They are amazing and he has over 90 episodes with a ton of information.
https://www.chameleonbreeder.com/ As far as your question of enclosure for one. I went with the Dragon Strand Clearside enclosure. The top and 1 side panel of these are screen for airflow. They have a drip easy pan you can get to control your water run off as well. By far the best on the market in all my research. Here is the link for these.

My 2 cents being new to this. To do it right it is expensive. I did not do proper research before getting my Veiled Chameleon. So I spent a lot of money getting the wrong things that I was told were right. I have since replaced everything bought initially. I have hit easily $2000. You are looking at getting the correct enclosure, lighting, mist system, food, supplements, live plants, and additionally temp gun, Solarmeter if you want to guarantee your UVB lighting levels at basking, humidity, and heat level monitoring devices. Oh and don't forget the Vet. Getting a poop sample run for parasites is important as well. Plus having a Vet that truly does know how to treat Chameleons....
On the plus side they are absolutely amazing and I could not imagine not waking up to Beman each day and seeing his little face. I have a great amount of respect for him and the joy he brings is unmatched by anything
