Prodcuts and Catagoreis database for B2B Marketplace

We are developing a B2B marketplace website by a developer now. We need to do: 1. Products entry to the marketplace (Marketplace PHP design under development now by our developer). Products details such as pictures, titles, Brands, Barcodes, specs etc. 2. Categories, subcategories, and sub-subcategories for all products. (we will work in industry categories one by one) 3. Import bulk products data from different sources by bulk look up or API. (Before you look to the sources, we must see the source in order to confirm since some products not in our target) 4. After importing all products, they must put in a database file. 5. Filtration tools for products and categories. 6. Duplication of the same exact product not permitted. 7. There are many brands in the market they sell alternative products. Alternative products are very important in our website and the database must link all alternative products together. 8. UPC/EAN barcode are also recommended to be in the products data. 9. Once our developer finishes the marketplace, you will import all the data there. 10. If there is any service is provided by third party service provider in the project, we will pay for the service to the third party. 11. Every product must have a special number (our marketplace number, SKU) 12. Pictures and content writing for the (Categories, subcategories, sub-subcategories) as per a sample we will share with you. Note: We are intermediate website which we do not sell the products, but we connect sellers and suppliers together and we want to build a good library of products to enhance the users experience. Note: The marketplace must have thousands of products in our industry (Products related to restaurants, hotels and hospitals) Note: Our target 1 million SKU. Above than this, we will open another job for the same amount (Percentage base) Note: Many of products not for retail sales (B2B industry and you might find them in special sites sources) – We will give you the category and you work to find sources plus we will give you our sources too to expedite the work You will work directly with us and our developer to execute the best results.
