Serenity: Sounds like a _great_ plan! There are plenty of books on partnerships, I've read that setting one up right is really important but the payoff is very high.
For my maintenance needs, I've got a few resources. My local A&P shows all new plane owners how to properly change their oil for free, for instance. Also, my EAA chapter has a few A&Ps that can be technical advisors on issues and monitor repairs I make, it's a great resource.
But it's probably hard to beat getting into a good partnership with someone who knows their stuff.
