Hi,
My 2 cents worth
Affiliate Marketing is still one of the most cost effective advertising mediums therefore any company should consider the set-up of such schemes as a long-term investment, just as your affiliate partners do and will.
Invest in the program, by that I mean use a network that is and can be trusted, there are plenty to choose from, a couple have been mentioned above by pricethat.
Employ or have someone to run/manage the program, look after your affiliates, this can be either in-house or outsourced to an agency or individual affiliate-marketing consultant. Ensure you have banners/creative’s, incentives, promotions and content for your affiliates, these are the basic (what I would call the sales tools) that your affiliates/partners would use to promote your site and offering. In addition, invest in the site and products, it needs to convert visitors to sales, affiliates will not spend hours promoting you and sending you hundreds and thousands of visitors if these do not turn into sales. As pricethat said, some of the networks can also help advice on this before launching a program
I
am sure some of the Networks would also be happy to look at how they can set-up different commission levels, hold commissions/sales on pending until they have booked this then becomes a real sales.
I guess it is like a pre-order. I
am sure some DVD/Games companies must have something similar, when a DVD is pre-ordered; the sale is pending and does not become a real order until the DVD is released.
This method could work for you, if I have understood your product correctly
Good luck
Stuart
