Source manufacturer and arrange fulfilment logistics for a patented new product

My company has an innovative new product for use by adults. It needs to move from design to production, be listed on Amazon and other e-commerce sites , and then have fulfilment logistics arranged to bridge the gap between ordering on a site to delivery. I am looking for a freelancer with experience in those areas who can arrange each step. Production won’t be in large volumes at first and most of the expenditure will be on marketing so I am looking for a HK based person with experience in all those fields and some Mandarin skills to deal with suppliers
