Hello there, greetings.
As I am concern you are looking for someone who can check the in term of grammar, spelling, and punctuation errors. I would say that I am good at proofreading as it is the final stage of checking a text before it is published or shared. I will focus on correcting minor errors and inconsistencies. I would be able to work on it for 20 hours for my weekly limit. Looking forward to talk to you soon! Thank you.
Thank you for reviewing my proposal and looking forward to your positive feedback.
Regards,
Yang Aini binti Ghazali
