Proof reading for a non-fiction book manuscript

Description

I am looking for someone to proofread a manuscript for a non-fiction book I have written. The book is approx 90,000 words long and am hoping to get the proofreading completed asap although urgency is not necessary. I am specifically looking for help with the grammar which I know needs to be improved and also with advice on editing. I do have a relatively small budget but would appreciate help with this project if this is something you may be able to provide
