Create 4 Joomla registration forms and an admin view/edit of data

I have a Joomla site at [login to view URL] and I need to add 4 vendor registration forms that also go to PayPal for payment. The forms contain much of the same information so it might be desireable to combine them and just have people select the options they want and complete data for those options. I want a vendor to be able to fill in the appropriate data, then they are taken to the PayPal cart with the price already filled in and they can check out from there. After payment they are take back to one of our pages. We need to send three notice emails to let the admin know that someone registered. This data needs to be captured in MySQL tables and allow the admin to see and edit all of the data for all registrations. Forms should have Captcha. Also, I want the winning bidder to include one hour of training on the forms so that I can do any modifications required later.
