We require a php programmer on a regular basis (flat fee per installation or hourly) to install twsc affiliate software. Generally, this installation takes 1-3 depending on programmer skill. AT THIS TIME, we do have a urgent project to install for one client. Ususally, we have one to two per week.
To further clarify: To 'install' is to install on the server and integrate with the site's design. We usually do this by creating a page called become_an_affiliate.html, in the design of the client's site, with an iframe that calls the signupaff.php (I believe that is the right filename). Also, someone here will be responsible to create two or three banners for the affiliate (the ones that have to be put in the banners directory) so banner design is not part of your responsibility.
