Manual Shopify product uploads

We have a shopify store. Our dropship supplier has a wholesale website that we need to transfer selected product range including pictures descriptions and related Items and more to our shopify account.

Please note,: our supplier does not provide any csv files or any data feeds. Everything will need to be done manually and with precision and quality control.

Please reply with your salary expectations and timing of completing this task. Keep in mind that it can be upto 1000 products that can be taken from 3 different supplier websites.
