starting a new nutritional supplement company and selling on amazon

I am looking to launch a new company to market and sell herbal supplements. I am in need of help to create branded product descriptions and list content, as well as design, packaging, and overall marketing strategies. I will provide the powders from vegetables and fruits to make the products. The freelancer hired for this project will be responsible for helping bring this nutritional supplement company to life and ensuring that it is successful plus step by step the opening of sales on Amazon (all documentation and support).I look forward to working with you to create and launch this exciting new venture!
