Hey thanks Lee for taking the time to help me with it.

On the first point, i think you are correct, i will outline all the things that make my group of sites stand out from the competition, and why they should choose to business with me. Some webmasters have told me they just want the facts and do not care about a big sales pitch. I don't think i need a big sales pitch per se, to promote my group of sites, however i will outline what i offer. high quality exclusive content, award winning photography and video, so i will make sure affiliates know what sets me appart and why i am not just another affiliate program.
Yes i am planning on mentioning on a point by point basis the no traffic leaks, hosted content etc. So it is quick and easy for webmasters to get.
Yes maybe i was being to generous on the webmaster referral, i think i will reduce to 10%
I have hired a part-time affiliate manager to start, that will be available for webmasters questions, special requests etc. He will also keep them up to date on new content updates, site news and other promotions i have planned. One advantage of also owning a video production company, is that content is not a problem for me. All my sites are updated weekly, i will also be adding new photo sets every month for my webmasters. I was planning on releasing several sets to my webmasters, a week before the model even appears on my site, so the content will be fresh and new.
Thanks Luke for you advice on the hosted galleries, as you know Stephen will be helping me on this, and i will make sure he is on it. I also realize that alot of it is building trusting relationships with your affiliates,and being accountable. Even though i do travel alot, i am planning on leaving my contact info as well as my affiliate rep.
