All the big stuff already seems like it's covered but ask yourselves why you got into the game.
For me it was the mini's but the Henchman I first got a demo from didn't play any mini games before this one. He loved it for the story and art etc. Leave the books and a few models near you when playing a game etc for people to see. The game may well draw in people you would not have thought.
I seem to have it the other way, with people playing in clubs but no lgs stocking it, so as ratty says, try to generate interest at some local clubs, they will have to buy their stuff somewhere and that may draw them to the lgs
