I am working on building a domain specific platform to showcase portfolio,connect and share with global audience. Community driven ( reviews and flagging fake service providers). Open to public to consume services ON-DEMAND (like Uber for "this domain" ).

Individuals offering their services in this domain make on an average 20 - 40k per year in US.

Problems I am trying to solve: * I would like to increase my clients average income. make them more marketable.

I just would like to focus on this very specific domain. I have no plan for revenue generation as of now.

Is it feasible to let users use my service for FREE ? If I need to scale, will VC's be interested in investing if I have a large user base ?
