The reason i am here

Hello everyone! This is my first text in English and I expect to write it well but you can correct me if you see any mistakes. The reason I am learning this language is that in Spain it has been increasingly important to speak English if you want to get a job. Actually, I am looking for any practice to improve my knowledge about communication. These  last four years I have been studying for a university degree, and now I want to work in my area.
Today, I am a little depressed because I realized that it's going to be very difficult to find a job in my country. There are a lot of companies that are looking for students to work for them, but they don't give salaries. It's very outrageous! I try to keep myself encouraged but it is difficult with this employment situation.
I have been thinking of going to England to work. Many people tell me there are a lot of jobs in London. Furthermore, I think traveling is the best manner/way to improve my English.
