I need to automate uploading and updating contacts, phone numbers, emails (bi-directionally) from a google sheet and into a new source that can serve as a free CRM. I'll also need help connecting this to Twilio so a freelancer can cold call (multiple calls at a time), and phone numbers would then need to be automatically updated with the status (invalid, valid, etc.) in both the free CRM and google sheet. Last, I need this to connect to the [login to view URL] API so that calls and prospect information is logged. I'll need a freelancer to design and build this, and then teach me how to build this so I understand how to modify everything going forward. I would also prefer to reduce costs, so would ideally like to make calls using the [login to view URL] system to avoid additional charges with Twilio.
