semi-formal letter

Dear Sir or Madam,

I am interested in applying for the job of a guide on your walking tours in Europe.

My reasons for wishing to join the team are that I have always been fascinated by the history of towns and traveling and I would very much like to exchange enhance/ improve my knowlage knowledgeby beeing a guide very much.

I would like to work in England , because this country has plenty of interesting places to visit and to tell  talk about.  

By the way,  I would like to ask for some additional information. Firstly, I would like to know if there is work in groups or alone.   In your advertisement you mentioned that I will need a knowlage knowledge of English, I wonder what the exact level required and I would like to know the exact level required.  I have an intermediate level which is quite enough to communicate without any problems. 
Also, I would like to know about accomodation and salary.
 
I look forward to hearing from you soon.

Yours faithfully,

Victora Krasova

I changed some syntax, I changed your paragraphs a little & I added a closing to the letter as well as an introductory sentence for the paragraph where you ask for more information.
