Ok, these people were the first ones to claim the job:

Gianluca95
roslinpl
conteaza
Candystripes

So no one else should start working on it now.  I can't offer everyone the full amounts listed in the OP, but I'll divide up 1.5 BTC as fairly as I can based on the results submitted.

For those four, whenever you have a completed list, please send a decent-sized sample by PM and the total number of sites, and we can agree on an amount for the full list.  The bounty isn't large enough to justify the effort to escrow.  Please review my posting history to see that I've paid for work here in the past without escrow.
