If you are already in the Turkey. I strongly advise to join English speaking communities in Turkey.
As like Toastmasters, JCI or any other NGO. Communities works! Once you meet with people they might help you to get landed on a perfect job.
If you haven't been in here. My humble advice is to make a focused research on the internet. What is the most generic thing that you can add you add into a company. Decide and filter the options into the limited numbers. So you target specific companies and write them, to their managers.
