Hello, I see that you need help with and English speaker.
I know I can help, I've got a sharp eye for things and I know you'll be happy with the results.
I'm very good in the English language as it's my primary language.
I've worked with various different types of project ranging from website, articles, and documents so I have experience in all those areas that will be to your benefit.
I know that with what you're looking to do I can greatly help, I know you'll be pleased with the end result and will be very happy.
Thank you for your time and I look forward to hearing back.
Do let me know if you'd like to talk further to go over more details.
If you're happy with the kind of work I do, I'd also like to open up dialogue for further work should you need anything together in the future as I believe in continuing and maintaining ongoing business relationships if it's mutually beneficial for both parties.
