I don't want to rain on your plans. I'm sure you have good reasons to pay whatever they've quoted you. Maybe it's just that bit of Scottish in my blood, but if we were sitting at the bar having a cocktail together, I would be handing you telephone numbers of folks who would charge you much less.
Either way, you will have a fantastic boat when you are finished.
Try contacting Guy Stevens. He's a great resource and not far from you. I was aboard his boat in October and I believe there isn't much he can't do. Heck he makes a mean guitar too (I want one for the plug Guy!)
