you've got plenty of chips... hopefully you've got around 100 or so of each color?

Start each player off with 3000 in chips and the starting blinds 25/50.

color a = $25 - you'll need 8 of these per starting player
color b = $100 = you'll need 8 per starting player
color c = $500 = you'll use 4 of these per player.

if you have enough of color b chips, start each player out with at least 13 and possibly 18 and just give them less $500 chips... it makes them feel like they've got more to play with while still keeping the value at $3000.

once your blinds get to $100/200 color up the green chips.

this is a fairly generous starting blind structure for a tournament... if you've only got 6 seats but 12 players then you should really run two seperate 1 table sit-n-go style events with the top 3 from each heat facing off in a final table showdown.

If you decide to go the sng route, start with 1500 chips instead of 3000. I'd set the blinds around 15 minutes.

dealers are a different animal. for buddies, as long as the cards get shuffled and someone is there who knows how to split a pot or answer dealing questions you should be good to go. if you've got 1 dealer who is also playing, have the button cut the deck after he shuffles.
