* give your reasons for wanting the job * you missed out this;  you did not say why you want the job; only what benefits it would give you not the company you are applying to. They want to know what you can give them not what they can give you. Try not to make your letter sound like you are maybe using them. 

Dear sir or madam

I am a student at the Faculty of Tourism. Currently in the final year of a three-year diploma course. I have an A level in English and French which I gained from the school of Languages in my hometown of Algiers. I have a keen interest in the tourist and hospitality Industry. I enjoy meeting tourists and assisting tourists to get a real sense of the culture of my Country.

I am looking to find employment that gives me the opportunity to further my goals of becoming a full-time manager of a tourist agency like your company. To continue to train throughout my career and to eventually be able to become a senior supervisor. 

Dear Sir or Madam,

I am writing to you with regard to your advertisement for the weekend job as a local tour guide.

I am a student at the Faculty of Tourism. I think this job would provide a chance to gain more experience in the tourism industry. In addition, I have been trained to deal with tourists and handle their inquiries. This was a considerable part of my daily study last semester.

Besides my native Arabic tongue, I have a very good command of English and French, so I am sure I can communicate well with visitors in conversations.

I was born in the city and I have lived all my life here. I have the necessary knowledge about all the historical places and most of the monuments in our city.  I will not need much time to be ready for work.
I look forward to getting your response.

Yours faithfully,
Muhammad Yahya

beside = next to 

besides =apart from / also.

"you will receive many comments from people who will tell you this is wrong, that beside = also/ apart from or that they mean the same" look in a good dictionary.
