Hi Fatih,
I am a native English speaker learning Spanish.
Something that has worked for me, is to join a Skype English learner's group as a native speaker. In your situation, start or join a Turkish group as a native speaker.
My only suggestion is to limit the size of the group to about 20 or less, then over time, remove people that aren't active. I would be shocked if you didn't end up with more than one person in your group that is a native English speaker, as well as others that have a high level of English and would be willing to help you. Just make sure to keep the Turkish group completely Turkish, and meet one on one or start another group for English.
I have gained access to a lot of people from all over the world simply by speaking my native language with them! What could be easier? In return, I have found friends that are willing to help me reach my goals as well.
My wife and I are both part of the English Skype group, and we have been for quite a while now. It's fantastic and it's more like a family than anything else.
My intention wasn't finding a Spanish partner, it was to help people learn and improve their English level through real conversation. What I ended up with was a bunch of new friends around the world, and a few of them are Spanish speakers that are willing to help me!
I just can't think of what could be better.
Best of luck!! :)
