Hi, Fabio -
In case you didn't receive our reply today via our ticket system on this request, here's what is needed to scope this work and provide a fixed price quote:
1) Temporary super admin access to your HikaShop store, so we can verify your HikaShop setup and configuration
2) A link to one or more sample products loaded into your store the way you want the final products to work (all variants, sizes, special fields, etc.). This ensures we understand the end result you want.
3) A copy of the Excel file with all of your data, so we can review the formatting and the organization of the raw data we'd be working with.
You can submit all of these items privately by replying to the ticket you opened with us. Once received, Polished Geek developers will review everything and I can then provide you a fixed price for importing your data into HikaShop.
Thanks!
