If you make so much profit, why don't you buy Bitcoins with wire transfer?
A Fedwire in the US I think also comes within an hour? Or not?http://en.wikipedia.org/wiki/Fedwire
I can sell you some coins, but I accept wire transfer only, not some fake-money like Paypal.
The only way I'd accept Paypal would be with a 180-day waiting period after receiving the Paypal transfer - then it becomes real-money.
Its not the matter of not trusting you, you can be honest, but if someone paid you with Paypal money from a stolen account, and then you pay me, when Paypal will try to reverse the transfer and you have no money in your Paypal or checking account to cover the loss, Paypal will reverse your transfer to me to cover the reversal.
Get an account at some bank which has outgoing wires at a reasonable cost, then you'll be able to buy Bitcoins fast.
