Online Product Demo, Contract acceptance, Payment Processing

I am soliciting bids for an online educational demo prefer macromedia captivate/flash animated presentation that will guide visitors through a complex product that ends with a call to action to "sign up now", present contracts, gain acceptance of all terms, and enter payment for the service. There must always be a "call me" option button for users who do not want to sign up online. This would be the first of two similiar projects.
