Payfast Integration Form Payment - Joomla

My website Is running on joomla. there is an event coming up so a booking form was created using proforms, a link to the registration form is here: [login to view URL] I need this form to be a process of : completing the form> paying according to which radio button is selected next to "Gala Dinner"/ or the option to pay later via EFT, > email being sent to person who is booking with details of what was registered as well as a invoice/ Receipt for payment, as well as the details being sent to the booking administrators. So basically, if i want to attend the event, i will navigate to the website, find the booking form, complete the details, choose weather i want 1 single seat or a table booking, then proceed to the next page where i will get the option to either pay immediately via payfast ([login to view URL]) or choose to pay via eft, if i choose Payfast then the payfast button for the relevant option which i chose will present itself. once o have paid via payfast then an email including a invoice and receipt will be sent to the client with the booking details, and an email must be sent to the booking administrators to inform them that the client has paid and the client details. If i chose the eft option, then i must be forwarded to a page to inform me of the payment/ account details, an an email must be sent to the client stating the reservation for the booking is pending, and will be approved upon payment verification. and an email must be sent to the booking administrators advising them of such pending reservation.
