Data Entry from bank statements to spreadsheet

We need approximately (very) 250 items from bank statements / a spreadsheet Sep 2018 - December 2019 to be transferred onto another spreadsheet.

We will have code all items with one of 14 codes (a, b, c etc). There are about 14 tabs on the spread sheet form and you need to enter each item (date, payee, amout) in the appropriate column on one of the fourteen tabs. Straightforward data entry but we need it done very quickly (24 hour turnaround) and very acurately. And the job needs to be finished. Half done is no help to us.
