Dear Sir/Madam,
I hope you are well.
Your ad caught my eye. As a fast, accurate touch typist (80+ words per minute) that has worked for 7 years as a Communications Officer for various inter-governmental organisations including the United Nations FAO, Bioversity International, ODI, and IIED, I certainly have the skills required to carry out this task.
If you are interested, I would be happy to send a CV and discuss further.
Best,
Joshua Jolivet
