Joomla site payment module integration use xfers

This is a project that needs to incorporate Virtuemart the plugin option for joomla , into the site for the purpose of 1. Get the services info such as the service name, the price etc from a mysql based table thats already existing, and display in in our site to sell 2. After the Service selection by a customer and checkout, provide the payment options such as Mastercard, visa, paypal etc by a Payment gateway that should be compatible with Virtuemart. 3. After success payment, generate the invoice and undertake some customisation of the existing php code for the purpose of the Registration. 4. Indicate all database records that are part of this entire workflow such as the before tax total, the tax amount , the final amount. 5. Handle recurring payment automatically as indicated by the customer. Hence during the payment, the must allow the customer to indicate that they would want the same service to be automatically renewed upon close to expiry date of the service and be charged and invoiced automatically also to them 6. Handle refund of the payment amounts both partial and full refunds. Because the existing site permits cash refunds as well hence this must also be taken into account when refunding. The design of the refund will be provided. Freelancer can suggest the payment gateway that they have used before (prefereably the same region as that of me the Client) . As this project needs an experienced hand hence anyone not familiar with Virtuemart and or never done anything about this NEED NOT APPLY FOR THIS JOB. Thank you.
