Hi there,
I have read though your job description about social media posts, I am interested in working on it., I can assure you that I will be a great asset to your graphics designing team as I have been working as a professional graphics designer for the last 9 years, so you will get top-quality well-researched designs for me, I am okay with the monthly salary. Hopefully, will get an opportunity to prove my worth as I have been doing for the last 9 years. Please knock.
