Integrate eBay API store with Wix Corvid API marketplace

Developer must have experience with both eBay API and Wix Corvid API. We currently have an eBay mens luxury clothing store with 7,000 unique items. New items are added daily. The eBay API store must be synced with our own database and then synced to the Wix Corvid API marketplace which needs to be built out. We currently do not have an ecommerce store on our wix site. Items sold on either platform must sync live to the database to remove the items from the other platform in near real time. Please do not contact us unless you have prior experience with integrating with an eBay API store and setting up an eCommerce store on Wix. These are hard requirements. UPDATE 7/30/19 - Please find updated information to clarify what is required for this project. Please find the detailed information below. Currently we have an ebay store and this store has 7000 unique preowned mens luxury clothing items. We only have 1 of each item. We want to mirror image our ebay store with all live items into a very simple easy to search WIX store on our own website so people can buy items from us directly outside of using ebay. The key is that the WIX store syncs with a database connected to our ebay store so that when an item sells on one site (ebay or wix) it is removed from the other site. Ideally the system you create will do the following. 1) Sync all newly listed items from our ebay store 1 time per day into our new store database. This includes downloading the image files to a server, both large images and small thumbnail images, all item specifics, consignor code, custom SKU # and custom measurements located in the html description of the item through a <findme> code inserted into the ebay listing. 2) Auto populate these new items into our WIX store (which needs to be built) so they can easily be purchased "OUTSIDE" of ebay through paypal / credit card. 3) Have the inventory sync system; Sync items from ebay to our database and put them into our Wix store 1 item per day at @ 4am est Check eBay for sold Items every 5 Minutes to update database Check eBay for unsold Items every 60 minutes to update the database Have WIX tell ebay instantly to remove an item from our eBay store when it sells in our WIX store Update with WIX store to make sure we do not have empty categories of items every time the “check sold items” is completed Have the database check the ebay store prices one time per day and update all items in the WIX store with the price 20% lower then the eBay price 4) The look and feel of the newly created WIX store should be something like these sites. This is a clothing store. There needs to be a way to easily search by brand as well as pick different categories of items Categories and details setup like this!
