360 machining work?

Hey everyone, so I just picked up a small block 360 for free, the engine is over all in very good shape for sitting for 15 years except for some surface rust in the cylinders. So my question is how would it cost to get the cylinders bored .030 over and also how much would it cost to get the bottom end balanced? If any of you have any tips on building a reliable performance 360 I could use as much information as I can get, thanks.
