Sir,
My name is Antonio Nogueras. I am a native Spanish student at the University of Kent currently in an intermission year to gather experience and money prior to continuing my studies. This will of course allow me to commit myself fully to all tasks you assign me.
I was awarded with the Cambridge ESOL CAE exam (C grade) in 2012 and I would be glad to provide you with the evidence and further on to demonstrate my level has greatly improved since that date.
Further on, I have also come to master French as I have been living in Brussels for 10 years (2003-2013). I also own a diploma by the Alliance Française (DALF, 90%) certifying my level of expertise.
I am the most suitable person for this job because I have a passion for words and writing and I am a voracious reader. I have owned for the last several years 3 blogs where I have written texts (mostly in Spanish, the language I absolutely master of course) ranging from poetry to short story tales, and even political critiques, economic dissertations or philosophical essays. I would be glad to provide you with all of them too, and show you my thoroughly developed language skills and demonstrate I can write interesting and pleasantly-reading texts on any subject you assign me.
I am the person you are searching for, and if you provide me with this opportunity I guarantee I will exceed all expectations.
