Proofreading Social Studies Book

I need a proficient English speaker to check a 50-100 page social studies book for spelling and grammar. The proofreading should be focused on basic spelling and grammar checks, without the need for detailed language and style edits or fact-checking. There is no specific style guide to follow, just a general check for correct use of English.

Ideal skills for the job:
- Strong command of English language
- Attention to detail
- Experience with proofreading and editing documents
- Ability to meet deadlines
