I currently live in the US. My family back in my home country run a factory that manufactures towels all sizes and all types. What is unique about them is that they are 100% egyptian cotton. They deal with several supplier chains around the world and ship around 400 containers yearly. I wanted to expand their shipping network and deal with big US supplier chains like Amazon, Shopify, Walmart or Cosco. What is the process that should be done to make an offer with such US supplier chains ? Or should I try by contacting local suppliers to offer them our product ? Its just that i feel that i can ship tons of 100% egyptian cotton towels but don't the process to sell and distribute the product.
