Needed: Proofreader. Will pay $20

This should not be too difficult, but proofreading is not my expertise. These are notes from a research observation at a high-tech company, essentially writing down everything they do in a work day. It is five days of notes, with each day having about 8-14 pages of notes, single spaced. Much of this is dialogue, and doesn't need to be changed (indeed can't be) except to check for spelling. Other than that, the rest just needs to be checked for misspellings, complete sentences, etc, and needs to be make, I quote, "pristine" for eventual use in published research. No content editing needed (like plot, theme, etc), just looking for errors. Should be pretty simple. Will pay $20. Native English speaker please. I can send you the doc files and then you can send it back. Need it back, at the latest, within 24 hours of receiving.
