Thanks for the help. I will find an A/C shop in my area and give it a shot. About pricing for the components, the compressor is about $170 on ebay, the condensor is about $100, and the evaporator (the cheapest genuine one I found, although ebay ones can be had for $100) was $340 but it came with a new expansion valve.
