Dear Sir/Ma'am,
I am a published writer of two books. I have also co-written the script of Back to the Future 4 which is currently under development. I have the experience and the knowledge necessary to handle this project. I can also provide you with a sample of the film scripts that I have written.
If you happen to award me this project, I will give my best to make your episodes a bang on the bucks.
Thanking You,
Yours Sincerely,
Mercator
