I'd second what everyone else has suggested. Doing service projects with other groups (Greek or not) is a good way to get your name out there and meet potential members that are outside your normal social circle.
Another thing that you guys could do is e-mail other organizations with information about your upcoming events (rush, service projects, fundraisers) and ask them to read it or pass it around at their next meeting. Our school has mailboxes for each student organization -- on occasion we'll pop flyers in everyone's mailbox and they usually get read at meetings. You could also go speak at other organizations' meetings (pick a few that you think would be really good to speak at, or have pairs of sisters go to two or three a piece).
Our school has a community service list, and we post our events on there occasionally -- do you guys have something like that?
You could also encourage each of your sisters to join one other organization on campus where they'd meet new people -- that's how we got a few of our current sisters.
(And Koah, I'm so sorry I couldn't make it to y'alls initiation! But Nu Chapter was thinking of you guys that weekend!)
