cPanel Features List for Hosting only MySQL Databases

Hello, I would like to create a hosting plan with cPanel but to only allow hosting of MySQL databases. Do you know what features should I include in Features List? Users will only have an option to register a subdomain, so no domain registration needed. While ordering they can only create a subdomain like ____________.myhostingsomain.com There will be 2 products: 1. MySQL Hosting 2. MySQL Hosting with SSH access Could you help me with the features list that I should include? Thanks, Davor
