Joomla IceBooking Accommodation payment gateway integration

My client has given me the go ahead and we need the following: The site is going to be using IceBooking ([login to view URL]) to process and Mygate (South Africa) to receive payments for bookings. IceBooking currently only has Paypal as a payment option and I would like an additional payment option added for processing payments through Mygate ([login to view URL]). We require the ability to create the booking in the admin area and automatically send a booking confirmation e-mail with a link to make payment. When payment is confrimed an e-mail should be sent confirming the booking and the accommodation confirmed in Icebooking by updating the availability calendar. We need this done in 5 days with a few days to allow the client to test and advise if there are any issues. I would prefer to make payment once the project is completed as I have been ripped off a few times by developers. Please only bid if you have a good track record of completeing projects on time.
