I totally disagree with the 'get a laptop and do it yourself' suggestions. If this is the first time you have recorded the results will be poor and no doubt be no better than you have.
Even already it sounds as if this may be a little technically out of your league (which is fine) so what I suggest you do before diving in yourself is get a little stack of cash (£200 is a good starting point) for a whole day in a cheap studio and watch how engineer set everything up, sound checks everything and runs the session (this is more important than the other two). Your simple observation in this one day will be infinitely more rewarding than a week with the laptop on your own. Ask him some questions, when he moves a mic, try and work out (with your ears) what it has done to the sound.
Once you have done all this, ask him more questions at the end. Be involved (observant if not hands on) in the mixing and, once again, try and clock whats going on.
Then, once this is all done, go get a laptop and apply this experience yourself. Expand on what was said, did and make lots of mistakes and experiments but don't expect studio quality recordings at the start. Keep at it and constantly refine on the basics and you will start getting good results.
If you try to do it all yourself at first you will find yourself worrying about all sorts of strange and nasty technical things when, in actual fact, the most important thing is playing well.
