Dear sir
I have carefully read and understood the conditions and requirements needed for the job.
I believe that I would be able to contribute and be a match for the position by applying all of myself, my knowledge, skills and all of my efforts.
In addition to my dedication, and perfectionist nature to produce a thorough and great job, I also have quite some free time at hand.
I am familiar with Englsih language like the back of my hand and also have a good knowledge about how to put up an artical as i have been writing them on various topics in the university.
I would truly appreciated the opportunity to help you and thus be given the chance to amaze you and maybe establish a long standing work relationship.
I am available to start immediately
