Use the 10 to buy you a decent board from a lumber store (or a wheelbarrow handle from the hardware store as long as its ash or equivalent) and build a real bow. Don't people build stuff in the UK? There's gotta be some lumber somewhere over there... oak, maple, etc. I know oak grows over across teh water. Buy a handsaw and cut down a sapling of a decent wood, debark it, seal the ends and dry it over the next few weeks in stages and make a bow from it. Or, while your maple's drying, use your bowyering time to read TBB's and study this site.
SS you have the opposite problem I had... I wanted to research everything to death and was so scared of screwing up i wouldn't touch the wood i bought, when what i needed to do was get after it. Chill out and slow your roll, and do some learning while you're waiting. Course i'm sure most of this has already been said somewhere.
