Currently your theme is tightly integrated with PayPal for billing and cycle billing. However, I am in Lebanon and PayPal does not work with this country. So is there a way to have different gateway system? if not, at least can I bypass the Paypal and have it "Send me an invoice"? The website I am working on is http://site13.iqservices.com/ it is a directory listing for companies that deal with Weddings, from car rental to florist.
As paypal is the main payment gateway for this theme, I bet that you will have to custom code something yourself to send own personal invoice on approval click, so that it does not re-direct to paypal, and sends your invoice instead. Not too sure how you are going to do this, however good luck.
