A unique referral based program

[Darren Rubendall]

I am in contact with an insurance brokerage that provides insurance products to doctors just out of medical school and also helps them to negotiate job offers. Later on, they will sell them financial planning. They work nationally, so their doctor clients land in cities all over the US. Because the doctors are about to see a huge increase in their careers financially, many will be in the market to buy their first home, normally $400,000 or above, depending on location. This insurance broker would like me to use my license to refer out the leads. Now obviously, I don't get paid until a deal closes. But how can I structure these deals? The insurance brokerage cannot take a percentage of the commission because they are not licensed. But, they want the lion's share of the money since they view my part as a sort of pass through. They plan to vet the agents in the other cities, so they see me as someone passing paperwork. It could be an income stream for me, so I am interested to give it a shot. I just don't know how to pay the insurance broker. It's hard to tell how many leads I'll start with, what percentage of them will close and in what time frame. A cost per lead model is not one that they favor, nor do I. It's too uncertain. We discussed hiring me on in some capacity so I am their employee, with the income flowing into me and I could then pay them. That doesn't seem right though.  Any creative ideas? Thanks in advance.
