Add products to Shopify Store

I have a Shopify store and a csv file from my dropshipper. I need someone to upload all the products from the CSV file into the Shopify system. You must know how Shopify work using Collections. I will expect Collections to be made up of the correct products. For example: mens jeans is one collection, womens jeans is another Collection. I expect the navigation to show something similar to next.co.uk. For example: one of the top menu items would be Men, then a subcategory under that there would be Jeans, Shoes etc. There are a few brands which cannot be uploaded which I shall inform you of. There are multiple variants for each product. For example a tshirt may be available in multiple colours and sizes. Where the product is the same but the variant is different, it must be loaded into shopify correctly (ie as a variant not as as a separate product). For example a tshirt that is black and comes in medium and large would be one product but 2 variants. The CSV file has all the information you would need including the SKU code and it also has the image urls. I can also provide you with a template CSV file that Shopify accepts. Payment shall be made once I am satisfied that the products have been loaded correctly. User *must* be fluent in English, know the Shopify system and know Excel.
