One way or another, you're going to spend money and/or time putting yourself where you can be found. Don't be afraid to spend money on publicity. Sometimes that's more efficient than putting in hours or "free" leg work. After all, your time is worth money.

Basically, you want to insert yourself into those moments and places where a qualified company is looking for a service like yours -- or, at least, would be open to hiring you if they discovered you exist.

You seem to be thinking mostly about scattering news stories about your company in broad outlets like TV news. However, in my opinion, you should look at more focused, niche advertising. Appearing on the nightly news once may feel good. Getting lots of likes on Facebook may make you feel like you're getting a lot of admiration and buzz. But how many of those people can actually hire you?

I'd look at 2 options: (1) SEM such as Google AdWords, and (2) Domain-based or content marketing. I have some sense of #1, but I'm a specialist in #2.
