Affiliate Links module for Drupal 6 - $$$

Hello

I need a module to handle outgoing affiliate links for multiple networks and sites.

Initially I only really need it as an API style module, i will call a function and pass in the original url and it will return a cloaked affiliate url. At a later date, we could add more functionality such as input format filtering, field formatters and launch on Drupal.org.

What it needs to do:

• There needs to be an affiliate provider system in place that lets the site owner add affiliate accounts for different websites and networks. Each provider account will have the affiliate id set and a list of urls/domains where this affiliate link will apply.
• When a url is passed in, it needs to pattern match against all the affiliate providers active on the site. If the url matches one of the providers, then the link is converted into an affiliate link and cached in the database for later calls. (If the url has no valid affiliate pattern it is just left as it is.)
• Then an optional cloaking/redirect layer is applied, that allows this affiliate url to be reached via a url on our own domain e.g. example.com/go/amazon.com/3425345. This should also have click count tracking (this part is similar to the gotwo module)

If you are interested in completing this module, please contact me with examples of your work, and an idea of the costs involved for this module.
