If you say where you're from, you might well find a breeder right here on BPnet. That's what I did when I got my girl.
As for the hides/water bowl, what wasn't mentioned is that these can even be just plastic bowls, turned over and with a small hole cut out for the hides. You can also use a planter saucer with a part of the lip cut out, which can sometimes look a little nicer.
For under tank heating, you can also use a piece of heat tape from Reptile Basics instead of buying a UTH, so you can save a little money that way. If you buy a wire/clip/insulator set with it, and ask for it prewired, Rich will even do it for free, so all you have to do is plug it in. http://www.reptilebasics.com/Heating-p-1-c-248.html
If you know anything about wiring and soldering though, it seems to be pretty easy to do it yourself. You can do a google search for flexwatt wiring and find a DIY guide. You just need an extension cord, soldering iron setup, and some insulating tape.
The only big money item left is really the thermostat. You can get a herpstat for about 109 http://spyderrobotics.com/products/herpstat.html it's a proportional thermostat which is really nice and will probably be worth it in the long run. You can also get an on/off Ranco from reptile basics which won't keep quite as tight control on your temps. One other option is to get a rheostat (I got a lamp dimmer for $10 from home depot that you can just plug your heater into and it's got a little slider to control the heat). The dimmer only works well if you have pretty consistent temperatures, but it might be a viable short term option if you want to save up some $$ for the herpstat
So you've got
$5ish for the bowls
$0 for newspaper substrate
$20ish for heating
$12 for Acurite thermometer/hygrometer
$10-100 for heat control
$15ish for a tub (not sure about that one)
$25-80 for a snake (good reason to not buy from PETCO- they're WAY expensive for what their snakes are worth)
