Hi @FELT314 ,
Try InventorySource -- https://www.inventorysource.com/ -- I use them for parts of my drop shipping setup. Travis and his team are first rate. Outstanding customer service. The platform is the best I have seen for inventory/shipping automation. A huge feature is the ability to customize your feed/products BEFORE uploading to your online catalog. They also have a HUGE product catalog from which you can select products.
Hope this helps,
