Custom Checkout + Authorize.net ARB Integration

I want a checkout page similar to Vonage ([login to view URL]) Layout of the checkout should be: Page 1 - The customer should be able to choose the plan(s) they desire. Page 2 - The customer should be able to enter their contact information and address. Page 3 - Confirmation page + credit card input. ---------------------------------------------- Information should then be saved in a MySQL database as well as transferred over to [login to view URL] via their ARB integration. Email confirmations will also need to be sent. Any questions, please feel free to contact me.
