Scraping stock levels in Excel using supplier's data (monthly)

Hi there!

We have a Shopify store and a number of suppliers, amounting to several thousand products.
We receive Excel stock sheets from each supplier, which contain data on stock numbers or a date when stock returns.

I would like somebody to review this data every month (it amounts to around 2,000 products) and update our own Shopify inventory with stock ETAs in the meta title fields as follows:

Delivered within 7-14 days
(for suppliers' items that are in stock or )

Stock due in early/mid/late MONTH - pre-order now
(for suppliers' items that are out of stock)

We export our Shopify data into a simple Excel sheet so all work is done in Excel. This will be a monthly task and I am looking for somebody who is a confident, capable user of Excel and has excellent accuracy.

Once the data is added, I will import the Excel sheet you send me into Shopify. Three weeks after, I will send you the exported file again to do the same, making amends where they are needed.

Please price for 1 month of data entry.
