This may be a long shot, but does anyone here have a half decent recording setup for guitar/vox?

I want to lay down some acoustic tracks, with overlaying vocals & harmonies for a track that will be the first dance at our wedding.

I can do the drum track, and the bass track in Ableton, but I want the guitar parts and the vocals to be my own, and although I can record them in Ableton, the quality is shocking through my laptops internal mic!

If anyone has a setup, and fancies working on a project with me, I'd be very grateful, and supply the beer!
