I'm so confused as to what methods of payment you actually ARE accepting?
And I'd be up for some of this as well if you'll escrow through John or someone else at this forum.
You say you have 50 BTC? I'll buy all of it for $5500 ($110 per bitcoin).
Where are you located, if you are within a 60 mile drive of me, I'll come meet you for the exchange and hand you cash. Otherwise we'll need to use a trusted escrow provider.
