Rather, I would appreciate your input and insight on the best way to conduct a large transaction like this in bitcoins.
Worst case, I post them on ebay, I have an excellent rating there but haven't used it in a few years.
I made some money selling 6990's on ebay just walking out to the store and flipping them (there's was never any shortage over here). I agree though their fees are nuts. If you do trust ebay but hate their fees. Perhaps you can use something like ebay as a means of establishing identity. For example require a successful sale of some small $1 priced item on ebay via private auction (which will cost you next to nothing in fees ). Then piggyback your BTC transaction on the success of that. You or the other person still have the option of hurting the others reputation if there is foul play (you could even require people with ebay ranks of a certain level ensuring they have something to lose).
Not a bad idea if I had someone that wanted to buy all 8. It would be quite a bit of work to jump through those hoops 8 separate times though...
You're in for a slice of the bounty pie.
