Since you have 16 years of experience, talking to all the people you have worked for and with over your career might be the best place to start.
As a rule of thumb, a good working hypothesis is that there are already enough contractors/consultants in the market to meet demand...or another way of thinking about it is that established businesses already have logistical solutions to their normal operational requirements.
This means that random potential clients won't be excited that you are suddenly available. They already have consultants. Those consultants work hard to keep them as clients.
Easy button websites for finding consulting work are races to the bottom because new consultants only get the worst work. Good work is regular well paying work and regular work means there are a regular cadre of consultant/contractors in that workflow.
Quite simply, contracting/consulting is not driven by performance but by sales. The easy button is Amazon Mechanical Turk.
