I agree as well with alot of the previous posts, guitars don't have any bite and a bit mid heavy, bass needs more meat, and the kick doesn't seem to really have any "punch" in my monitors. The cleans sounded great... but to put a price on your work like that people would need more to go off of, and it also has a large part to do with where you live and how you plan to record these bands. If you're doing just internet projects $100/song might be a stretch. If you're soaking up time in your day to have people come track in a halfway decent setting, $100/song is a bit of an undercut IMO. When I started out I was doing 150/song full production specials... but i poured tons of time and money into my facility, best bet is to do by the hour anyways.
