Hello - I close my prior project and I'm reposting this as I was unable to edit the Project Name. All bids I was receiving was from Big Commerce Site developers, while my real requirement was BigCommerce listing specialist. Please see note below for expectations - I'm looking for a Big Commerce product listing expert. Please read the description carefully as the it DOES NOT merely involve populating data into Big Commerce spreadsheet and [login to view URL] will need to be familiar with Big Commerce and showcase prior work. I run an ecommerce website that I'm looking to add new products to. The store runs on Big Commerce platform. I have the list of products from the supplier /manufacturer in specific excel format. The product range will include but is not restricted to leather handbags, non leather handbags, womens clothing etc. Links to the images are available and in over 99% of the cases are provided by Parent SKU and Child SKU. You will need to know how to create "options" within BigCommerce in bulk for all products to create variations of similar product (The one with the largest number of images would be the parent product sku and the rest would be child sku for each product). a) Use excel functions to sort, identify and classify parent and child sku (Could be around 1000 including parent and child sku's translating to 500 products possibly) b) Create options in bulk based on color and sku for 99% of the products, add other relevant info like google shopping categories, alt tags for images etc c) You will need to know how to leverage [login to view URL] to enable google not follow those sku's for which we have not written optimized content yet d) Format the file and load it to to my site through BigCommerce Admin Panel e) Validate results once uploaded and get ready for Phase 2 work If you are a big commerce and an ecommerce product upload specialist, I'm sure you would know the steps I'm missing. So please feel free to chime in. There shall be No Upfront Payments made. Only 2 milestones.
