What are the best places to get new affiliates?

I'm an affiliates manager for a supplements company and am wondering if you all have some ideas for obtaining new affiliates for our site. We currently have an account with ShareaSale and they are great. We have a strong core of affiliates we work with but I am interested in expanding it. It's been harder than it sounds!
Thanks for you help!
