I need a copy editor to bring a short book of 55 pages / 16500 words up to a professional standard.edit

he subject of the book is the extent of childhod poverty in Birmingham UK. I already have arrangments in place to self publish my book....but before I submit the book for final formating / cover design... I just want to have the contents copy edited. The self publishing copy editing process takes 3 weeks which is longer than I had hoped.
I am anxious about upoloading anything here as the contents is embargoed until 1-1-22.
Could any replies please assure me of their confidentiality policies.
Thanks Eddie O'Hara
