Word forms tidying up and Pdf creation

I run a web design company here and a client of mine has 400 word documents which we need to:

1. position the logo in the top right (as the one attached)
2. change all the font colours and headings etc to be consistent throughout. in both size, colour and style.
3. Table lines need to all be consistent thtroughout all documents/forms

I would like to see how much you would charge for this project?

The documents are in word at the moment and I have attached one of the forms for you to see. If you would be happy to do the work I would make a master style on this form for example so you could copy all the others to match.

Happy to work another way if you have an idea.
Kind regards Rebecca
