shopify drop ship store

I am looking for a professional to help me update a few things on a Shopify drop ship store with a budget of less than $500. I already have an active Shopify account, and the store will feature a wide variety of products that range from clothing and accessories to home and kitchen to electronics. I'm looking for someone who has experience and knowledge in setting up successful Shopify stores, and who is able to optimize the store to meet my needs. The ideal developer should also be familiar with product listing optimization and marketing, in order to ensure the success of the store.
