Hello,
I am not sure if you are willing to cooperate with a private. Still, i recommend myself for this task. I think i am qualified to complete all the jobs you mentioned here. I have been engaging in foreign business for 7 years with working experience with Costco and some individuals from US.
I don't have the license right now, but if you could hire me, i can register and apply for the license immediately. Or you could hire me as your sector in China. I know the whole export process and the benefit of export rebate which could help you lower cost.
I don't think "kickback" is a problem at present. Many things are changed these years. The new generation are no longer following the type of their fathers. As my experience, the supplier will stop if you refuse to accept any "kickback" directly.
I know the food regulation of FDA, so i think it is not hard to learn more about the health care products.
Hope to get an opportunity to work for you.
Thanks
