Ok I have a couple of questions, but here's the deal.

Basement is 1/2 finished. The half which needs concrete has a dirt
floor right now and has some heating pipes as welll as the walls are
old flagstone, it think. So, here are the questions.

1. How much prep work can I do on my own?
2. How much do you think it migh cost to put down the floor? (figure
30x30) or so.
3. the dirt gets wet, I think it seeps UP, not from the walls, so will
taht dry out the basement?

Thanks
