Selling Licenses

We are looking for a freelancer who can help us to sell software licenses in woocommerce.

I have pdf licenses with diffrent key codes and i need to let the customer download the licenses immediately after purchase, i try many plugin but all is not matching my concerns, our licenses has two codes same as itunes or playstation cards but my cards has two codes and it has generated to pdf.

Moreover, we need to make inventory that show us which licenses has sold to avoid any duplicate sell.

Licenses only use one time, thats mean no one can use same file.

Our website has builded by wordpress and it has woocommerce.

Here is sample of licenses.

Thanks.
