Hello again. well it sounds as though you have some of the major issues covered. Help, scaffolding etc. Besure you give that thing an up close and persomal inspection before quoting a price. As far as that goes I don't really know what the price would be within your area. But up here at the least ,the very least it would be between 12 and 15 grand for a single color paint job. From what you have told me so far,things are fairly well in hand. Getting help is the biggest issue,so thats covered. Your initial out lay on marerials are what you really have to keep under control, this can and will kill you if you don't keep tabs on it. Since your also doing graphics, I think somewhere between 15 and 20 grand is in the ball park.but again that will depend on the prep work that is required. As an example a tank and two fenders on a bike is $1500, that seems to be the going rate up here. So to me 15 -20 on something that size, and the amount of time and work involed is not unreasonable,or at least not up here. But it sounds like you're up for it,so go for it. But before you do just make sure you do some serious number crunching. One other thing to consider is that if the customer is a friend,he or she maybe expecting some sort of deal. This you will have to be careful with. Hope this helps you somewhat. Let us know what you decide. All I can say is that being involved with one of these beasts, I would not do it again. But to be fair I did not get any help.
