Finishing basement

Hi,
Dh and I are looking into finishing our basement to make a playroom for DD. The previous owns already did most of the sheetrock. Can someone give me an idea of how much it will cost to finish? We aren't putting a bathroom in and it does need heat. After doing a search a lot about waterproofing came up. What exactly does that entail? Any info you could give would be greatly appreciated. Also, if you could
recommend your contractor as well. DH thinks that he can do a lot on his own, but I'm a little nervous about that!

Re: Finishing basement

I would think that the waterproofing had to be done before the sheetrock.
