Well, DIYing a solution based on VHO might be a solution. Many of the online aquatic stores sell a variety of components.
Another thing you can do is get yourself a Jebo/Odyssea system. I found a 36" 192 watt compact fluorescent system for 80 bucks online, that may actually be your best shot. That would give you 6wpg, so you could keep most of the easier corals (leathers, mushrooms, torch/hammer) and even possibly a low light clam like a t. Derasa if you are careful.
I found a 36" metal halide system for 180. This would allow you to keep anything you wanted, except be aware that Odyssea systems have halide bulbs that can be hard to find, and the older generation metal halide systems had problems with starting fires (although supposedly they fixed this issue with the newest systems).
Make no mistake, these lighting systems are low end chinese imports, but many people on this board like them for their performance vs. price. I personally build all my own lighting systems, but I realized after asking about your building skills that even then there is little chance of meeting your budget.
Keep in mind that the lighting system is usually one of the most expensive components of a reef system.
