Website Ecommerce Multivendor Multishop B2C B2B Development

I want to build an e-commerce site in Node.js framework (Full stack) that will have multivendor and multishop features and will be able to sell both physical and digital goods combined with services (Mostly booking of services).The vendors must have their own profiles and shops and-or to be able to enter their own payment gateways allowing the platform to take a [login to view URL] website will be a B2C model but if it can be combined with B2B functionality and ERP features would be [login to view URL] except from the main site's blog if a microblogging feature to the profiles or the stores of the vendors could be implemented that would be [login to view URL] to be mentioned the social login of vendors and users is considered defacto and the one page checkout too. I need a freelancer or agency that is well informed about the open source universe out there and be able to work well with these open source solutions and to combine features through source code programming or api. Also the core of the functionality of the webshop must have modular architecture according to the MVC model for easy future implementations and [login to view URL] out of the box thinking in this project will make it stand out and the success of it will drive to a continuous co-operation.
