Math text editing - non-college math EDiting, proofreading, math checking

PLEASE READ ALL PROJECT DETAILS BEFORE BIDDING TO AVOID BEING MARKED AS SPAM Hello, We need someone to proofread a book and look for mathematical as well as obvious errors (typos, bad punctuation etc...) The book involves high-school and physics related math but no calculus. I need someone to review and proofread this book. Looking for major errors of math and any errors in answer keys, problem solutions. But also looking for small things like typos, bad comma, parentheses use, etc... Should take about 2-3 days to go through the 223 page book in that level of detail. I have attached a sample of the book to give you an idea of the work/level of detail involved. If you take job I will send the book as a .pdf. The top priority is major errors of math, followed by typical book errors. Clarity, grammar, the usual. PROJECT DETAILS: The book is ~ 223pages, the project is estimated at 20 hours of full time editing/proofreading. As such, the editing MUST BE COMPLETE IN 2-3 DAYS. The final book will be sent as a .pdf so any changes should be tracked via excel sheet or, if you have the capability, convert the pdf. to a .doc and use MS word track changes. SO long as formatting, clarity, page count of the book is not altered. Any edits will be noted in the attached excel spreadsheet. Milestones can be created for each 100 pages. 100 pages would be expected per day for editing. Do not enter low bids just to walk up the cost. The timing and budget for the project is set and can not be changed. See attached files for examples of the work. Upon acceptance a full pdf will be sent.
