Marketplace are the most difficult model to build. It is like building 2 businesses. One that is a service provider and the other that is a demand generator.

Essentially you are selling two products to two distinct sets of consumers and being the market maker. Make your Business stories that their needs.

People who provide solution in clarity don't do it for $. No on does 9-5 clarity calls for living (unlike Uber). When an expert has this feeling to share his knowledge to a needy person, clarity provides a way to do it.... So you need to identity where the appetite lies and how to sell it..

Even if you have lot of leads at both sides, it needs a lot of try and error to reach the right equation where to have an optimal supply-demand ratio.

Feel free to talk.
If you don't have the seed users/consumers for both sides, you have start building it and gradually in a controlled manner start introducing them to both sides of the business until you perfect the right mix..

like Flour and Water - when it comes to bread making... :-)
Happy to read if you want to share what your business is about. May be we can do a 3 mins brainstorm after that..

My strengths are
- How can you use technology to measure the KPI
- Design systems and processes in place to achieve this goal.
