Hi there, I can make this website for you with a back-end admin panel secured with login credentials where you can showcase your items. On the panel you will be able to add/remove/edit items, view contact requests and add other admin accounts to use the panel. The front-end view of the website will be based upon what you like and I will first do a mock-up design in Adobe Experience Design before coding and designing the website with a live preview link. I am able to give a free months web hosting while I make this for you. If you have any questions, feel free to message me.
Kind regards,
Ben
