Hi, i will be soon launching my new site and i was wondering if there is any good affiliate networks that offer maybe a free service and take a retainer from each sale, i know the set up can be expensive to run program but i need to start on a small budget. my site is a horse racing tipping site which brings some good profits and gets lots of winners.
i will be charging a monthly fee (money back return if you dont make money) to customers and i need to get this out to the public with little advertising budget

Can anyone help to point me in the right direction?
