Sponsors would be good and maybe you could get a church or something to host the raffle for you (I could make a quilt for you to raffle) or if actually have non-profit status for what you're doing with the dolls you would qualify to do it yourself, and then get them to "donate" the money to you once they're done?
That said.. for those.. I'd say something like $20. Shipping is hard to figure because of different distances costing different prices.
