Proofread Children's Activities

I have 468 children's activities such as the sample below that I need someone to proof read. The activities range from around 70 - 200 words each. The activities come in 9 categories of 52 activities (many have accompanying worksheets) in each document. It takes me between 20 - 30 minutes to read each document. I would anticipate this job to take approximately 4-5 hours to complete. The applicant would need a CANVA account so the activities could be shares with them and they will be able to make corrections directly in the document.
Applicant will need to proof read for the following:
- Spelling and grammar
- Headings correct?
- Does the 'You Will Need' section list all required material?
- Do the activity instructions make sense?
