You can quite easily make picks out of hacksaw blades or street sweep bristles. Since I think you OP said you don't have power tools then you can always use hand files (which you can pick up fairly cheaply at your local Home Despot). If your looking to buy picks you best and cheapest source (unless you have a business you can use to purchase from a supplier, which I doubt) is online,
www.lockpickshop.com offers a 10% discount to site members with the code 'LP101'
and the rest of you grow up I'm sure he only needed one person to tel him to search... the rest was redundant and immature
