Dear Sir,
I wish to apply for this post and i wish to say that this is my area of strength. I have got every capacity to do a good job on your project.
This is not the first time i have done this, i have got experience doing this type of jobs, and i'm sure i will do a good job for you.
I believe without much talk you can as well hit the hire button, or rather have a discussion with me . I will be looking forward to your response.
Thanks
