Blinda, apart from a few mistakes in your text (a native speaker should have a look at it), I'd write something about the company. Why did you choose this company? What do find useful, impressive etc. about this company?
Just another suggestion: leave out the sentence "I would like to ask if it is possible ..."
Don't be so shy and modest. Tell something about yourself, about your skills, your knowledge, what you are interested in: draw attention to yourself! Why should they offer YOU a position and not somebody else? What do you think? What could you tell them to answer this question?

Good luck!

Yours Sincerely,

Snowcake is right about giving the company a reason to take you on. You have adequately explained what you'll get out of it. But you haven't offered anything in return. (Apart from promising to snoop around, analyse the company, make some possibly damning conclusions about their company, and then take their trade secrets to your next placement.)
I know that sounds facetious, but shouldn't the manager think about that?
You haven't said that you intended to benefit the company.
