Tamster:
You didn't mention what size boat you have. If the boat is going to have to be slung out of the water for the work, you might want to start by calling various haulout facilities. Most of them have a short list of mechanics they allow to work in thier yards, if any.
If your boat is on a trailer, then the sky is the limit. If fact, you might want to check with Desdemonia at the space station/bait shop. I'll bet she knows of some out-of-this-world deals.

By the way, any one seen my canvas? It was on the boat a few days ago, I swear..
