Contact Importer Membership Site

Looking to create a contact importer membership site using amember membership software. Site will allow users to copy and paste javascript code onto their website pages. This code will have a contact importer that can import from major email services ( gmail, hotmail, yahoo, aol, etc ). Backend should be able to customize message, track invites, get javascript code specific to user, etc. Should be able to scale in the future to myspace, facebook, twitter, etc. Design of website should have web 2.0 look and feel. Can show you example sites and code. Let me know if you can do a project like this. Also looking to retain services monthly if job is done well.
