I have heard nothing but horror stories about trying to buy/sell BTC on paypal. I would advise you to stay far far from it. Though this is quite a clever solution to the problem.
Sending a redeemable code (solid paper) via traceable shipping on eBay is the best way to sell over PayPal so far.
If you can find buyer domestically you can profit up to 200% from bitcoins.
If buyer tries to refund you'll just need to upload the track paper over eBay as a proof so you're safe.
