Welcome.
I noticed your other post about tearing free from banking institutions and was wondering if you could elaborate a little more on this desire.
There are a lot of other angles to exchanging fiat to BTC and then to GoldCoin, but it may help to shed some light on your plan to narrow those recommendations down.
Most methods that incur greater risk for the seller, increase the premium over the base prices you'll encounter on the exchanges. Hence, the safer the transaction (like ACH to a checking account) the lower the costs incurred by yourself.
Cash in hand and conversion to methods accepted by other conversion methods such as buying Linden Dollars via VirWox is possible, but it might help to get a feel for what your goals and methods desired are.
Cheers.
