Paypal, amazonpayment, dwolla, etc.... they're all reversible. You'll need much more reputation than that to be paying with these methods. It won't matter if you go first or not, or how high your rate is.
I doubt you'll get any hits on this, so I suggest looking for another payment method. If you're willing to do a bank cash deposit, I might sell you the btc, depending on the rate.
Tbh I'm only doing this because I'm bored and all I have is amazon payment to pay for my WoW sub haha.
