One thing I can tell you is it is gonna cost more than you think.
I don't see how it could cost less than $15k. and as GlassDave said above I'm talking for an already de-rigged boat, one color, no graphics. The amount that of work that goes into painting one of these boats is unbelievable. I had to see it with my own eyes to understand how time consuming it is and how much work. The more you spend the better paint you will get, if you try to cut corners on painting a boat you will be wasting your money in the end.
