Dear Sir/Madame,
I read your project and as a social media manager I am very interested in managing your social media for marketing your business. I have high proficiency in English, with IELTS 8 results (level C1).
My managing services include channels like Facebook, Instagram, Twitter, Pinterest, LinkedIn, Google+, and YouTube.
I would like to discuss with you on the management period, budget and delivery deadlines, as well as any other specific request you may have for completing this work.
Looking forward to hearing from you!
Thank you for considering me!
