I've modified the title of your topic so that other integrators may see your request.
I'm happy to answer questions about HubSpot's APIs and capabilities, however you will need to work with a developer or team familiar with REST APIs in order to connect ProvenExpert to your HubSpot account. (This isn't a project that should be handled solely on this forum.)
Besides the community members here, I can also recommend the certified agencies on the HubSpot Partner Directory. I've filtered the search results to only surface partners that specialize in building custom integrations for clients.
Please let me know if you have high level questions about integrating with HubSpot!
