Whatever you do, do not get discouraged. My chapter is very small also. Last Fall, our Rush was very unsuccessful. We had an event every day for a week and all together we only got about 15-20 people to show up. We ended up with 2 pledges and then one of them dropped

. But we ended up with a REALLY good brother who was very instrumental in helping us double our membership the next semester.
As a past VPM, I will offer this advice to you. Your chapter should make a policy that each brother is responsible for getting one pledge per semester. This is something that is easy to do if everyone gets their friend to pledge. If you start off with a small but cohesive group, it will make people really want to join.
