You're looking at having to master (or at least become proficient at) about 5 different things before you can go hunt with the gear you make:
bow making
arrow making
knapping
string making
shooting a primitive bow

I don't want to discourage you but next year may be a little optimistic unless you've got a lot of free time on your hands. There are folks that have spent years on just one of these subjects and still consider themselves beginners.
