Bear Archery has some decent bows to get you started (that's what I'm using at the moment). They're somewhat affordable and good quality for the price. I'd recommend a bow kit that comes with everything so you don't have to try and piece it together yourself..then just upgrade as you progress.
Depending where you live, there's probably a bunch of ranchers/farmers within driving distance. Support local as much as possible...seems like a lot of 'em are opening up to #bitcoin as well
