It looks like Kevin Hinkle (Previous Lego Employee) himself has listed a bunch of auctions and one of the auctions has all 7 varieties of his Lego Employee Minifigures. This looks pretty nice and I urge you to check out all of his auctions as he is getting rid of some very nice items. You can see it here.
All seven straight from Kevin Hinkle. Version 1 to Version 7 🙂
Thanks for looking
