It is a very good idea to have a consultation marketplace for finance experts. The customers will be able to ask questions and if they find suitable answers they can get on a call with the experts. Since you have already found answers to the questions below:

- What is the problem?
- Who are your target audience?
- What do they need and what problems do they face?

Once you have a clear idea of How will you make money from this business model, it's time to develop a working prototype for your marketplace. This will help you test whether or not there is enough demand for your product and also determine if it makes sense as a business.

There are many online marketplace scripts that you can use or you can create from scratch.
