Introduction of product information onto Shopify-2

ONLY FOR FREELANCERS WITH EXCELENT ENGLISH SKILLS Hello all, I am launching an online shop and need someone to introduce product information/images onto shopify. The information is to be retrieved from PDF catalogues I have and also from the supplier's webpages. The information required to introduce for each product is a description, images, video (if available on the supplier website), dimensions, weight, price, category and brand. Some product catalogues may have 3 products, other may have 300 so I want the price given for each set of 500 products. I want someone which is interested and if needed goes the extra mile as this is a long-term project and if you do well I'll continue to use you for this. So far I've entered about 1000 products and that is not even scratching the surface. The way I want to do this, even though I'll be paying per set of 500, is: - I send you the brand details, PDF catalogue and list of items that are to be done per brand - You use the catalogue, supplier website and others website (if required) to collect the information required and introduce it onto shopify according to the information template I'll provide (the information is to be placed according to a specific order) - UNTIL I'M SURE YOU'VE UNDERSTOOD HOW THE DATA IS TO BE ENTERED YOU'LL HAVE TO ENTER 1 PRODUCT PER BRAND BEFORE GOING ONTO TO THE REMAINING ONES. THAT WAY I CAN CHECK IF EVERYTHING IS OK AND AVOID WASTING TIME (YOURS AND MINE) - At the end of each brand you'll send me a checklist of what has been done so I can verify your work - After I review the work I'll release the correspondent amount (if the bid is 100$ for 500 products and you've made 50 in 1 brand I'll release 10$ as soon as everything is verified, which will be done 24-48h after you submit your list.
