I then converted the USD to bitcoins and sucked up the "fee" MtGox charges for the privilege of keeping my money indefinitely. After trying to find a suitable way to transfer the BTC out and convert it into fiat, it became clear that the charges to do so would be exorbitant, as all the exchange services are not setup to convert large amounts of BTC to fiat and their fee structure makes it impractical.
I strongly recommend you withdraw your money in Bitcoin in small steps (400 BTC/day or more if you're verified), and sell it on other markets. Put a buy order for something like 4.95 USD/BTC (not to loose to much money), and wait. Or even 4.92 USD, the price might drop a bit to the levels of 11-14 May - just a few days ago.
Because with time it might get even worse. MtGox might "pull an AML" on you, it might take another some weeks or months or you never know.
You must have not done a very good job searching at other exchanges.
Your sum is just 5200 BTC. That's just about daily volume of Intersango on GBP. Its just 2 days volume on
http://www.bitcoin.de/ and you can get quite good prices there - but SEPA only.
There are several other markets. This is not such a huge sum, you get this liquidated to fiat in a week or less.
What country do you need the wire to?
Put some one sale on
https://bitmarket.eu/market/USD and advertise it on
https://bitcointalk.org/index.php?board=53.0If you offer a good price (4.89 USD or less) I might be interested in buying by wire to anywhere in the world, in portions of 1000 USD a time, and I sell the BTC off in Europe and buy the next portion. Lots of other people would do the same probably.
