I know the cost of finishing your basement will vary greatly depending on a bajillion things, but, being a noob at this, I have no idea how to even go about getting a ball park figure. The basement area is 19' x 29' x 8'. It's totally bare right now. There are two small windows and one door. I would want, basically, one big room. I could do the framing and drywalling myself, but would hire someone else to do just about everything else (especially the painting ). How can I figure out a rough estimate as to how much this would cost? Any guesses? Just too many variables to determine a number?
