i'm not sure of the rate but pc bells take a while to add up, so i'd probably put them at 1 tbt = 100 bells or so?
if you're still interested i can trade.
how it works: you friend the person you want to give you the bells and post things in your market box equal in amount to how many bells you want, then the other person buys the stuff out of your box, leaving you with the bells.
