you can use a lot of recycled materials for things like your hides... so they can cost you nothing.

a rubbermaid type of container is great for balls. won't cost you much at all. you just use a drill or a soldering iron to put some ventilation holes in the sides.

UTH is the best heat source - a human heating pad is not and neither are overhead lights (as they dry the air too much).

you can use newspaper for substrate which is also free.

and a website you can get most of your needs from Matt:

http://www.mgreptiles.com/

i've never ordered from him, but he seems to have a good reputation on this site (i'm relatively new here as well)

i'm sure others will chime in with more info soon.

and welcome!
