So, from what you say, you need two things: more money and someone who has RF knowledge.
Money
* Day-job: get one and work on your project on your free time (or wait until you have saved enough money, and work on your project full time)
* Rich guys: Investors, VCs, a patent-buyer.
And about the RF knowledge
* A partner: you both will work for free and you will share the future benefits
* A hired RF guy: you pay him, and you get all the future benefits.
* If you opt by the rich guys, they may help you under their own terms.
But also remember that you already have a very valuable thing: you have been in several startups, so you have experienced that there is a boring part -paying bills, marketing,...- that has to be done, and more important, you also know the people behind that startups, who will be able to help you and provide with you good advice (much better than mine) and contacts.
In fact, forget this comment and call them.
One problem that i see, is that it can be very easy to game the system.
Let's say that the advertisers pay a fixed monthly payment. If I were an advertiser and my advertisement were run every time that three women are in front of the screen... well, I'd hire three actresses so that they stay in from of the screen: my ad would be shown lots of times, and adds of my competitors would never be shown.
If, on the contrary, the advertisers have to pay for each time his ad is shown, and my competitor's ad is shown when the system detects three men... well, in this case, I'd hire three actors to stay there, to force my rival to pay, pay and pay.
Like the fraudulent clicks in AdSense, but in real life.
