Ideal Clients

Your job is to create value and find people who are willing to pay for it.

How do I find those people who are wanting to work with me? I have around 500 connections on LinkedIn but almost all of them are not my ideal clients.
For example: My ideal clients are new female entrepreneurs
But most of my connections are male people in IT companies.

And even if I have my ideal client how do I know if they are the ones who want to pay or want to work with me?
