We Need to Integrate Facebook Custom Audiences and Offline Conversion Events with ClubReady via API

ClubReady is a CRM for fitness studios. It does not offer webhooks or “push” changes. We would like to take prospect and member (aka customer) activity and send it to Facebook to: (1) create/modify Facebook custom audiences (2) add “lead” and “purchase” events to Facebook offline conversion event sets. We would start with one store as a test, but I'd like code written so that it would be easy to onboard multiple stores (e.g. 5 -10 minute setup time for a developer or even option for a user interface where a layperson can add a store). See attachment for detailed functionality needed. I expect the you to follow the specifications exactly as described. I used to be a software business analyst so I understand that sometimes you may run into unforeseen circumstances. I would like to be consulted on this because the integrity of the script and data is very important. I am looking for a freelancer that has a lot of experience with API work and scripting to ensure the logic and specifications are met. Extensive work with the Facebook API is required.
