Hello there

As someone who has his own business development agency and also advises on Business Development, I will only share how I would feel towards such a proposal.

If we are partners, than it is 15%; and at the start, yes, I expect you to close the sale, as I am learning your product and your closing techniques regarding this product.

I believe your biggest problem is finding the right people; I don't believe you should spend much time on figuring out the perfect compensation plan.

My advice, go with 15% and spend the time in getting the right people and invest in helping them succeed by remaining motivated.

I know, a lot tougher and time consuming than a few percentiles.
