What % would you give a promising inspector partner in China?

What share would you give an inspector partner based out of China?My research indicates many “transactional” relationships are 5% to 10% of the product cost. I want to have a true partnership and incentivize the inspector to care about the health of my business back in the states and think net profit although higher, is more aligned with a long term prospect.He owns his own plastic bag factory and has a rolodex of local contacts should I want to branch out and has been diligent and quick moving.I have struggled with a good %, and suggested at one point 10% of net profits. Is that too high? What arrangements do you have with the people you work with in China?They will:Inspect the productHave workers package the product (this is likely a separate small fee)Help find additional products in the futureThus far:He Helped find the factoriesHe visited factories, collected samples and sent to usCoordinated samples to be sent to usThey won’t:Negotiate pricing, they prefer we do that. see hubwealthy.com/wealthy
