I need to create and edit a bulk import catalog products on csv file for Cdiscount.com marketplace.

Hello, I am from France, I can speak with you in French, Spanish and conversational English, I am sorry for the errors in English I speak it better than I write it, I am looking for an expert in data entry with Excel and bulk products import. I need you create for me a csv catalog products file with variants (article number, sku, ean code, size, color, short description, long description, composition, stock, price, vat, image 1,2,3,4,5 .. .) for different marketplace like Ebay, Amazon, Etsy and my principal listing marketplace CDISCOUNT.COM.. All of these marketplaces have a specific csv file type template and we need to make some changes and organize our csv according to their file template so that it can be mapped and uploaded to my storeS marketplace.If anyone can do it at low price, please feel free to contact me.PS: I work with different brands and some brands provide me their product catalogs ready to be download in csv, xml, excel, pdf ... just we need to make some changes and copy to our csv file.
