List my Amazon products to Rakuten, Sears and Newegg

Hello - I'm an Amazon seller. I'm looking to expand into multiple marketplaces with Rakuten, Sears and Newegg being the top of the list. I already have accounts with all 3. I would need an ecommerce data entry / feed upload / sales channel management expert to - a) Extract my existing listings from Amazon b) Create Feed files for Rakuten, Sears and Newegg c) Load feed files and images and do everything needed to set me up to sell For now the product listing would be a combination of cell phone accessories, tablet accessories and clothing For Newegg the listings would be exclusive clothing and not the phone or tablet accessories To bid on the project, you would need to exhibit past experience doing the exact same activity (not a similar one but the exact same activity) of managing seller marketplace accounts and creating product listings. I'm not looking for someone to pick each listing and add them individually as it would be time consuming. You need to have expertise with the respective platforms and should necessarily know them in and out as I expect that you would list them fast. Please place bid for for 100-150 product listings (not quantity but products) range. Note - I'm not looking for sales support. I'm looking for product listing expertise within these platforms. Happy bidding.
