Change font/ style of word doc + Long term work

We are looking for someone to reformat about 50 word documents, this simply means:

- Changing the font style/ size/ margins to the same set of requirements (to be provided) that will be the same for all documents, as well as adding a header, which will also be provided

- We've tried this ourselves, each document takes 1 minute max to fix

- This needs to be done by Saturday 23:59 GMT, deadline is NOT negotiable

- This is a trial task for our Education Consultancy business. Successful completion will lead on to long-term work
