CB Subs to buy or not to buy?

I am a relative newbie. I do not know php, I can make minor changes and that is about it. Here is what I need to accomplish can it be done with CB Subs? Could I do it or will I need to find a professional?

I need to sell classes to registered users. Once the user selects the class they will have to add the exhibitor and the name of their horse for that class and once finished check out. I really would like the user to be able to add records to a database in their account and select from those records as a drop down.

Is this task going to be to difficult for me? I have created a website and I am currently using Joomla 3.5 and CB. Are there videos or documentation showing me how to accomplish this?

CBSubs is subscription management. It doesn't provide the ability to collect additional information beyond what is needed to make a purchase. So the additional information you're wanting they'd supply at time of registration or in profile edit using standard CB fields.

There are backend views for subscribers, payments, etc.. in addition to filters in CB > User Management to filter your users to specific subscribers. Additionally a userlist could be used if you wanted this on frontend.

We've a few CBSubs videos below.

There's also some usecase tutorials below that utilize CBSubs.

I'm not entirely sure CBSubs fits your needs though, but it could work understanding the limitations noted above. Sounds like you're needing more of a shopping cart type or storefront like usage. Alternatively there's standalone solutions like Moodle specifically setup for teaching/lessons that maybe able to be used for what you're wanting.
