I am a student who struggled a lot while I was searching for online editing services, here I will guide you on how to get the best service.
Look for a service with experienced and qualified proofreaders.
Check for customer reviews and testimonials.
Consider the type of document you need to have proofread and choose a service that specializes in that area.
Consider the turnaround time and cost of the service.
I hope this helps! Let me know if you have any other questions.
