Perhaps ask her if you can stick a small poster or notice in her LFS to invite anyone interested in saltwater keeping in general & reefing in particular to contact you. Who knows how many anonymous reefers are in your area. It may just be you, it may be a dozen, but at least it'll get the word out.
BTW, most places don't really have a formal reefing club yet or are just starting out, but the advantage they have is knowing a lot of the local reefers. Your first step, IMO, is finding out if there are other reefers & if so, getting in contact with them.
Once you get a few contacts, then you can all decide whether to go through the extra trouble of organizing a formal club or to just keep in touch with each other occasionally.
Hope that helps,
Anthony
