Hi,
Docile, hardy and inexpensive are gonna be hard to find in one species. But I'll try to break it down for you by each attribute your looking for.
Docile: Not too many chameleons are docile. However, of all the species, panthers(furcifur pardalis) seem to be the least aggressive. Veilds are among the most aggressive.
Inexpensive: Veilds are one of the least expensive chameleons ranging from 30-100 dollars depending on size. Panthers are one of the most expensive ranging from 175 to over 500 depending on size and morph.
Hardy: Seems like you already know that chameleons are not easy to keep. I would say that veilds and panthers are equal in terms of care requirements. I do know that jacksons are considered one of the hardier species, but I have no personal expereince with them. I'm sure someone on this forum can provide more info on them.
In regards to shipping, I will be honest and say that shipping does cause a bit of stress. But if the shipper does it properly, and does not skimp on the packaging materials, the animal will get there safe and sound.
For a first timer, I would recommend getting a male. With females, you run into issues of egg binding and additional care requirements for their health. I would'nt purchase a female unless she would be bred at some point.
The only other advice I can offer you is that you figure out if your budget has room for a chameleon. The chameleon itself makes up a very small portion of the cost in owning one.
And don't forget, chameleons need daily care. So make sure you can spend at least 10 minutes a day caring for him. And also provision for vacations. Will you be able to find someone to care for him while your away?
I don't mean to discourage you, but these are somethings that many new owners don't consider before purchasing.
Having said that, chameleons are not that difficult to take care of. YOU JUST NEED TO TAKE CARE OF THEM. All this means is that you need to pay attention to the animal, and the rest is easy.

Good Luck.
