Build an Online Store

Need a simple website that I can use to manage items that I post for sale on Facebook. Each item will need its own unique page that can be shared through social media. May not need an actual shopping cart, do not need to manage check out, payments or shipping. I need to set up an items with 6-8 basic fields (most text fields such as sale price, when to make available, description) Also need to assign a category to the item. Once the item is posted I need it to auto post to my facebook group page within an album, if possible. I need the main photo of the item to be the original post with the text entered for the item (sale price, description, etc) and any additional photos added to the listing to appear as comments on that listing on Facebook and appear as additional pictures on the website. I also need the comments to be shown on the item page on the website. Visitors should be able to post to the comments of the item either on facebook and have them visible on the website or on the website and have it visible on Facebook. Each item will be assigned a close date and time. Once that close time passes the item will need to be moved from the category that it was assigned to a different folder on the website. As for admin features, I only need to set up an item as described above and once it closed be able to mark that it was paid for and picked up. Once that happens the item should be archived on the website ( no longer viewable to pubic and deleted from facebook) In the future (Not part of this bid) we would like to add more features, such as: -View our items through our own app where customers can also make payment and search for items. -Manage multiple stores with the same software that will have the items posted to a different store (on a different domain or sub domain) and different facebook group Should have a look very similar to gofundme.com. Can be built in Wordpress or other CMS, whichever CMS allows us the features we need and ability to grow into future features.
