I would look for an established club near you. Don't think that an established club will look down on you since you are starting out. Most rocketeers LOVE to help new people and you can learn a lot from these guys (and the occasional gal).
I am sure it will be intimidating to see guys with rockets taller than you, but I don't think there is anyone in my group who would hesitate to help someone starting out. Our club sees rockets with everything from A to M motors. I did a count of a club launch we did in early December and we had A through K motors that day, but the majority was low power (A, B, C and D motors).
We launched yesterday and I flew 5 rockets; one each of A through E motors.
