How much would it cost to finish my basement?

my basement is about 600 sq feet. It has drywall on one wall, another wall (inside wall) has studs but no insallation. the two largest walls have insallation but no studs on them. The ceiling has studs but no drywall. Does anybody have an idea on what the cost would be just to have the drywall finished? Please give me an idea, without including carpet flooring. Can somebody give me an idea of costs with and without professional help? thanks!!!
