Hi and welcome to eBid.
Your photo on the About Me page looks good, very professional, however you will need to edit the contact details part. Is there any way you could upload the pic without the contact details, maybe just the store name? It would be OK like that. Otherwise you could use a different photo as HM suggested.
Per listings, you can add listed items to stores by editing and using the drop downs at the top of the listing, making sure to save your work when you've finished. Agree with HM, it might be a good idea to have a read through the Help section (check out the videos on setting up stores) and Astral's FAQs page. Contact info. (as phone number, address, links to external ecommerce websites, etc.) isn't allowed in listings or on the About Me page per eBid rules. Astral's FAQs page is here:

You also might want to have a look around the stores area, particularly the Health & Beauty section, (which is where I assume your store would be situated as you sell medical equipments), it might give you some ideas about setting up your store, particularly in the categories and subcategories departments.
Any further questions just ask and we'll try to assist.
