Hi,
I wish to express my interest in your offer.
I have an excellent command of English both in writing and speaking. I wish to be your visual assistant. Am very tractable and willing to learn what i don't already know but that is necessary for the task you want to be assisted with. I am a team good player, industrious and respect deadlines. My charges are negotiable.
I look forward to working with you. Kindly contact me for more details.
Kind Regards.
