Shopify account set up for a new Dropshipping business.

My name is [Client's Name], and I am looking to set up a Shopify account to launch a dropshipping business. My level of experience with Shopify is beginner, and at this stage I have not yet finalized a specific niche or product type. I am open to any product type that offers good prospects for success. I also need assistance with the marketing and promotion strategies for my Shopify store. I need full assistance with this, and am looking for guidance on how to set up and run an effective marketing strategy that will drive maximum sales.
