Hello,
Thank you for posting this exciting project, I'd love to work on it with you.
I can build out this feature for you, I can arrange a Skype session with you for demonstration purposes.
I consult with the biggest Salesforce partner (platinum reseller) in Africa, where I have worked on over 50 different implementations involving custom integrations, migrations, custom and external applications apex, SOQL and visualforce, lightning rollouts and many other odds and ends.
Kind regards,
Tawanda
