WoJo - costs are VERY dependant on size. But as a point of comparison:
Paint (the good stuff) costs between $200 & $250 usd a gallon (US) from a retailer. IF you intend to
DIY, depending on which yard you go to, you could be charged a "corkage" fee of up to 50% to use your OWN PURCHASED
paint. If you go to a
DIY yard, there is usually no additional
fees charged to use your own paint (and in some cases, it may even be cheaper to buy through your DIY yard). There is the hauling out fee and Lay Day(s) fee, along with the splash fee (putting you back in). Often times, they will charge a 're-blocking' fee if you want them to move the blocks and props that are used to keep your boat in place and upright (so that you can paint those covered spots), Clean-up fee, environmental fee, a fee to go pee ... oh wait .. maybe not that one... YET!
Each yard is pretty good about quoting those
fees. Some yards will also charge rental for various items (ladders, tools,
cleaning equipment, and so on). When they start nick'n you for every little thing, well - word gets about pretty quick and those that care, don't use that yard. There are 6 or 7 yards in the LA to SD areas, that do private boats (also depending on size).
Now might be a good time to mention what size (and configuration) is the boat ???
