eBay product listing and management

We currently have an eBay store but with only about 10 products in our store. However we would like to start listing more products and start adding them from our Shopify store where we have approx 4000 products.

Products would need to be gradually added and optimised for maximum visibility and sales.

We would need see previous work and explain how you work and what kind of results we could expect from your services.
