Checkout cutomization on an osc based website

Actually my osCMax website is working normally with a one page checkout contribution installed. The website is selling cannabis related products and my payment processor can't accept anymore payments made directly from my website. But my payment processor told me a trick. Instead of payments made directly from my website to their gateway, my customers may receive a payment request by mail containing a link to process the payment. by this way credit card companies won't know that the payments are coming from my website. And my payment processor panel has a function to send payment request by email. This function has to be automated for my customers to get immediately the payment request by mail. My website is translated in 4 languages so this new function has to be multilingual. HAPPY BID!
