Review 1 doc, a small slid deck and a power-point presentation

I've got 2 docs I need reviewing and checking for spelling and consistency - one is a 22 page document, one a small spreadsheet.

I also have a 10 slide (may be a couple more slides) Google Powerpoint (can be converted to PowerPoint) that I need to review and make look nice, snappy and interactive. I need the job completed by Wednesday AM. An NDA will need to be signed and if successful I have much proof reading that needs doing for website, proposals, LinkedIn articles etc. that will be upcoming in the future.

Please provide a fixed estimate of time required.

Thanks
