Asking the question "How do I meet other members for (insert intended purpose here)" is like asking "How do I make friends?"
If you don't know how to network with others (for any reason, not just for ritualization,) than nothing anyone here can tell you is going to benefit you. That's just something you're going to have to figure out on your own.
And, as an aside, many Satanists (not all... but many) are not all that interested in group ritualization. Ritual is a very personal, and very often private, affair. You'll be very hard pressed to find many Satanists that are willing to invite you into their ritual chamber without at least having developed some kind of friendship with you.
