API system integration

Three things that you need to know to bid on this project: 1) I'm planning to use webinars on the front end of my marketing model - the system I've chosen for that is Stealth Seminars 2) On the back end of the system I'm selling access to a membership site - the system I use is Studio Press Premise 3) My ideal client is often found on Linked In and that is where much of my webinar marketing will take place Recently I saw someone using the LinkedIn API to register people and gather their information for a free download. [login to view URL] I would like to implement their API to register people for a Stealth Seminar/webinar on the front end and also make it available to join the membership site on the back end. In the 'perfect' integration we will, at the same time add the name and email address to my autoresponder (currently Mail Chimp) As I don't know what is involved in implementing/integrating these public APIs into my site, etc, I've classed this as a simple project. Please provide a firm estimate based on your knowledge of the technologies I'm using (Stealth Seminar and Premise). Thank you!
