@Bill the barbarian it sounds like you have quite a lot of people in your area (1 million was it?) and mention about mainly DnD and mtg groups at your local games stores? The whole idea of being part of the club is introducing people who play those sort of games to the chaosium ones aswell as people who have ayes neither.
Ive had great success in the past by going to the local games shops and clubs where these are played to introduce players to CoC.
I just turn up on games night or talk to the owners or players before hand and arrange a table for the following week.
Even if you can get 1 or 2 people interested, over the week when thy are playing mtg or whatever else, they talk to each other. By the time the following week arrives I've usually got a full table.
It has led to some sales of the starter sets from the shops I'm in which has then led to many thanks from the owners and some free drink grub.
Think not what the cult can do for you but what you can do for you, by doing for the cult..... Push for what you want and chaosium intend to have your back. There is loads of material available for free as @Todd@Chaosium has already pointed out. He will even provide you with money for the chaosium store online if you get in touch after running events for free stuff (I've never bothered, wish I had though as I'd have quite a pretty penny by now).
For me the reward is the fun I have at the table, it's that simple. My area has a lot more people interested in what I like (Call of Cthulhu) because I went out and actually interacted with the diverse community and introduced them to what I like.
Try it. Make some friends, make some memories and come back and tell us all about it.
You got this brother.
