Worried

I'm a little over 3 weeks away from the Avon Walk for Breast Cancer - Chicago and I'm a little worried about meeting my fund raising goal. I'm still $440 away and I don't know if I'll get there. There are lots of people who I was sure would help, but haven't and I don't know what else to do! I started a raffle on May 1 and publicized it on Facebook and Linkedin, but all of those efforts have resulted in 1 entry.
