Finding good commission salespeople is almost impossible. I've hired companies who supposedly specialize in this, and no results.

Base+Commission is probably the best you're going to get. The base has to be slightly less than what the salesperson can survive on, which will induce them to go get sales. But your commission % must be high: at least 30%. Or competent salespeople will laugh you off as they walk out of the interview.

Honestly, though, and this isn't going to make you happy to hear, but as the business owner if you can't sell your own products or services, you're not going to make it. Nobody believes in your business as much as you. Nobody cares as much as you. Not your significant other, not your employees. And if you can't do it, no one can.

In your situation, which is essentially a startup in the rare situation of having some case studies to point to, YOU need to be spending at least 70% of your time on prospecting for new business. If you're programming, or supervising, you're putting your energy into the wrong thing. You need revenue. Now.
