A virtual nod to all member on this page; all good advice.
Here is another approach - traditionally consulting was centered around, "What do you need? I can do it better, faster, cheaper." I believe, the world has moved to an App store mentality. Unless you are Google and building your own switch for the scalable datacenter, there is pretty much NOTHING that you are doing that someone else has never done before.
My point, build a proverbial app (not a mobile app); something that solves a specific problem. It can be an approach, a methodology, a MVP, slides (you get the point). Something that says, you have done your homework.
Evangelize it for free, learn from it, refine it, charge for it. If there is value, your customers will find you and pay for it. Pretty soon, you will need more of you. I believe in "see one, do one, teach one" approach to build a team.
