You have to practice everyday. You need to learn to think in English. Surround yourself with the English language in everything, from books, to TV shows, DVD's, music, stick notes with English words for everything in your house so you become familar. Find someone to talk to who speaks English fluently.

I always conclude that learning a language is divided into two sides, input and output. Reading books, watching tv shows and listening to bbc are classified as input. Speaking with people, writing down something are classified as output. They are different. Input is a process that you comprehense others' thought and explain to yourself. Output is the opposite process that you comprehense your own thought and explain to others. The only way to be more skillful in each side is to do more of it. That is to double your english conversations as much as possible.

The best way is to find a native speaker/ tutor in your area just look up the adds in your local paper.

take a trip to america! :) and on italki, dont only chat through typing, but verbally too (talking)

Hi, Michael, another way to improve your english speaking skills is to listen to English or American radio or an audio, listen to their pronunciations and also watch english TV. Try to capture what they're trying to say, read a lot of english books, magazines and english newspapers. Good luck.
