I need someone to set up advertising deals with site owners in the herpes niche

Simple really, need someone with experience and expertise in finding and closes advertisement deals with people who own herpes related sites. I am looking for banner ads/forum ads/newsletter ads an anything else that will be beneficial. I own a herpes service and want to find places to promote it. The site owners have to be getting a lot of traffic to qualify and you will have to negotiate the best price with them and then check with me before closeing the deal.
