Add Products to Prestashop Online Store - Pro II

I need somebody to upload products to my Prestashop online store. All the products are Mobile Phones / Laptops / Tabs / Smart Watches. 420 item. You have to find and add description / specification / images under each and every products and create complete listing. For a example see these listings. [login to view URL] / [login to view URL] Preferred Requirements: (Optional) Web / HTML knowledge Data Entry Experience and Speed Basic Knowledge and items (Since these items might be specifically different each other by a letter of model numbers / ite will looks like same, but specifically different) Previous experience with Prestashop. This will be ongoing since we have more than 1000s other products to update in to the store. So I expect best prices + quality works, if this worked well, more will come. P.S. Milestone will create after project award and will be release as per products update. (Ex - First milestone payment will be release after 50 items listed in store... so and so - Can be negotiate after project awarded. ) Sorry to say but we had very bad experience with previous order; We WILL NOT release any amount of money before you start the project and until you complete the 1st milestone. Questions are welcome!!! If you interest please PM me. Then I will give you temporary login to create sample listing for me. This is Required*
