I've got the perfect guy -- YOU!
Stay with me, now...
You can find someone else to do this for you, but there isn't anyone out there who has as much riding on the outcome as you do.
Since you are contemplating hiring it out, make your first investment in yourself. Buy a couple of good books and start reading. You may find that while intimidating, the problems you face are not beyond your abilities. If you decide to tackle it DIY, you'll save a ton of cash on labor.
If after reading up on the subjects, you still decide to hire it out all your boning up ahead of time will really help when you are talking to the tech that tackles your work. You'll have a much better idea of whether or not he's on the ball or just interested in getting into your wallet.
A couple of recommendations:
- Nigel Calder's Boatowner's Electrical and Mechanical handbook
- Don Casey's Complete Illustrated Sailboat Maintenance Manual
- MaineSail's DIY blog posts -- home
I'm sure others can make additional recommendations.
All the best.
