If you are just looking for an affiliate tracking system: http://www.hasoffers.com and http://www.offerit.com are very cheap solutions that should be able to do everything you need.

If you are looking to add your "offer" to an existing affiliate network with an existing publisher base then you should look into Commission Junction, Clickbank, LinkShare, ShareASale, etc. Many networks specialize in different verticals. Be sure to do your research.
