Crwodfunding like social network - need help to complete few functionalities

Hi all,
I am building a crowdfunding social network starting from zerocode template “Crowdfunding like Indiego” .
One of the critical points that I need to solve is to link the flow of data from and toward google excel via a Google Sheet Doc.
In addition I would need to add further pages that send surveys and pools to main users into the network.
I understand there is the need for a minimum investment from my side and I would be happy to get help on finishing this website.
Anyone interested?

Sent my contact in a PM.
