Shopify store connected to Amazon

Hello. We have had a Shopify store for a long time, but have only used it for nonprofit donations for our organization www.globalfoodproviders.com. We need to develop a full store that features agricultural, gardening products that connect to Amazon and all order fulfillment is done through Amazon and vendors. We will simply take a commission for directing our clients that way. Can you help us set up the Amazon account, set up the base store so we can personally add the products we want, and make sure that the details are in place so we see income from sending our clients? We have tried this in the past but could not figure out how to get the Amazon account set up correctly so we could make money. Please let us know what you are able to do, and how fast you could get us up and running. Before holiday surge?
