Setting up WP to put customers & businesses in contact

Hi all!

Possible Newbie alert, so bear with me ??

Bottle in the ocean with a “uber-type” scenario.

I want to put prospective customers in relation with prospective businesses in a given sector. basically the uber-model (so I havent reinvented the wheel here)

Basically looking for a way to set up a website with 2 sides (customers and businesses), with secure login features, simple communication (chat?) and -why not- in-between commission fee.

CRMs exist but they are B2c in a one-to-many scenario. I want a many-to-many scenario with a community of businesses and a community of customers.

The simple concept is artists on the one side, venues for them to showcase their art on the other

Anyone know of templates or a way to set this up with WP?

Thanks
