for a veild 6 feet is fine... thats what mine is in... ... so thats not a prob... ventalation might be... now i dont think youll need 20 feet though... 5 by 3.5 by 6.. (lxwxh) is a very nice size enclosure.. screen is the best way to go...
heres a discription of mine...

a very in diet is good... i made that mistake... how would u like to eat only burgers... most pet stores will have them... you could always breed silkies... that would work...
youd really have to work out ventalation... that would be the only problem i could see...
heres a list of what youll need...
repti-glo 5.0 florecent tube and fixture ( as long as you can is best)
heat lamps... ( spot lamp should be fine, temp around 85 day time, and possibly none needed at night, night should be in the 70's but 68 can happen without harm)
GOOD QUALITY thermometer and humidity gauge ( a temp gun would be nice too, just to do spot checks of highs and lows and basking spot)
vines ( i made my own by brading grapevine that i cut off a wreath)
a few plants would be nice... ( hibicus and pothos is what i have but there not in yet and i cant keep the hibicus alive, there supposed to be harty)
and of course the cage...
this is bare minimum, some extras are nice like a helix temp controll a mister and stuff..
because you live in fl... some outdoor time is benifical, real sun and stuff....
BEWARE if your looking for something you can hold a chameleon may not be the best choice, there agressive and espically veilds...
youll also need a smaller enclosure that you can use when its small... to keep a close eye on its health...
as for fake plants. check dollar stores.... or walmart...
if you need anything else or if theres something i havent answered just ask ok...
oh and if space is an issue look for a dwarf alot smaller and only like 30 gal ( so ive heard) is needed... i like them alot and other that cresties thats my next purchase
see ya
