I would suggest posting some pictures when you have the chance. That way we can better give you an idea of what it's worth.
Right off hand 2000.00 doesn't sound to bad providing you can drive it home.
The rebuild you're asking about .030, would be normal. I would call Maddog and see if the have a .010 set. In this case less is better. The more you bore the cylinders, the more it could over heat.
But keep in mind we can speculate all we want, but until you take the engine apart and do some checking we're just guessing.
