List of Instagram accounts that are inactive

Looking for a list of Instagram accounts I follow that have not posted in the last six months.

I follow 1,000 accounts from a public account.

The deliverable would be:
+an excel or google drive spreadsheet
+columns : Instagram handle (linked), last post date

I will not provide login information to my account for this task.

I will also check against data I have before remitting payment to make sure the job has been done thoroughly.

Priority will be given to those who can do a quick turnaround!
