Hey kid bow,
Thought I'd chime in here. I am almost exactly one year older than you are. I'll be turning 17 on February 15th. I have been into this primitive archery stuff for about 4 years now and I have been trading goods with other guys on this site for probably 2 years now.
I started in your same position. No goods and not a lot of money. Here's what I did....
I bought a poplar board at Lowes for 3 bucks. Using only hand tools, I turned it into six beautiful atlatls. I tradeded 3 for staves and sold 2 for $20 bucks a piece. Using that money I began to purchase various things I needed. I bought leather purses and jackets at thrift stores, found old tools at garage sales, turned junk steel into functional knives, built and sold bows, making another $200 bucks into the process. Two of my bows are owned by members on this site and as far as I know, they are very satisfied. I have traded with as much generosity as I've been able to and have made small purchases here and there. Haven't had a bad trade yet and I've done probably 4-5 dozen. Youll find people are generous once they get to know you are a man of your word and do everything you can to ensure that they are just as happy as you are. I've never asked for something for free, yet the more deals I complete and the more friends I make, the more and more I find that people are willing to help me, and I would do the same for them.
I'm not trying to rip on you, I just want to let you know that it is possible to to turn nothing into something. Have a dream and stick to it. I can honestly now open my trades saying that I have a tone of stuff I can trade... All that from one $3 dollar board and a little elbow grease.
Good luck finding what you need.
Jon
