looking for a Data entry editing proofreader who can change files by editing articles proofread

I'm looking for an experienced data entry editing proofreader to help me edit and proofread a large number of files. The project will require strong grammar editing skills, as well as copywriting services to supplement the articles. I need someone who can quickly and accurately proofread more than 10 files. If you have experience with this task and are confident you can provide the necessary quality and speed, then I look forward to hearing from you.
