You're going to have to call around local places. The problem you may face (if it's used) is nobody wanting to do it if it's anything like where I am. I'm in Texas and I've seen this problem because they're required to provide a warranty service and nobody wants to warranty a system that they don't know the history of or that's used and purchased elsewhere. It's too much of a risk, so usually the ones that even consider touching it will charge a lot.
