Ebay Store design and mobile friendly listing template design

Ebay Store design and mobile friendly listing template I started my Ebay business this year so it is quite small. What I need is a good store design and a template to re-use for all my existing listings. My 41 current listings will need to comply with 2017 Ebay requirements and to the new store design. The listing design should include images of the item for sale as well as links to other listings currently selling. Information on existing listings regarding payment and shipping policies and item specifics can be used for information. I am also selling some of my items in the US on Amazon and Ebay.com if the first job goes well there may be future or ongoing work available, for new listings product research and sourcing of products.
