Hello welcome to the forum. Sorry I am joining in late, I was out of town. I live in Montana so my weather make yours look mild, from 100 to -30 We can help you have a very healthy chameleon.
If you can get to home depot or Lowes, try to get a ficus tree or a umbrella tree. Get one sized to fit your cage. Order the dripper tray when you order the cage, you will need it with a mist king. With the hours you are at work, the mist king will save your cham. The biggest issues you will face, with the hours you work and your weather, are water and temps. Both are manageable. The live plants will allow the water to stay available on leaves longer than fake plants. Live plants will also help you control humidity, and where you live that is sometimes a challenge. You will also need to get or make a dripper. Lots of easy ones make on here. Supplements are needed but I am sure Jann's blog or Kinyongia covered those.
I do agree the best chameleon for you would likely be a veiled or a panther. I would say don't go NEAR a pet store. We can hook you up with a sponsor or a forum member so you start with a strong, healthy chameleon. If you start well the odds are a lot better for you and your chameleon.
Ok I will shut up. (long sigh from other members). Please ask all the questions and between all of us we will get you answers.
