Im not sure which idiot will accept paypal from newbie, and also which idiot will also give his btc before he have the payment in his account based on the risk he take with paypal.
I have an established Virwox account with screenshots or even remote login to prove I'm reliable.
To prove you are reliable, you can start using bitcointalk escrow, also you can offer much way secured payment method to bitcoin sellers.
PayPal have nothing to do with secured payment method and also off-site feedback means nothing.
If you want to prove yourself as good trader/seller/buyer, provide security for both party such as "escrow" and payments which cannot be reversed.
Good luck.
