Cart for selling access to directory listings

Hello everyone,

I am developing a specialized, country-wide directory listing. The plan is to sell access to the content (currently stored in a MySQL database) on an annual basis and three options: Option A: access to lists from two regions, Option B: access to lists from four regions, and, Option C: full access.

I am looking for a cart/storefront solution to do this. I have used (set-up) a Bigcommerce site before but it was for actual, physical products, not access to specific content.

Is there a solution that can do this for me?

Thank you for your help!
