cheap flight searching engine for Turkey

Hello, I have realized in Germany that turkish people who want to fly to Turkey can not find the great price unless they check several airlines web site. Therefore, I bought a domain (turkish) where people can remember easily and look through the cheap flights for Turkey. (such as, turkish airlines, flypgs, sunekspress, germanwings, easyjet etc. etc.) So I need someone who is really experienced on this type of searching engine web site are very welcome. In case needed, I can provide translations for turkish. (for the first time turkish would be enough, but the platform has to support other language. There will not be a buy-sell on the web site (at least for now). So it is only cheap price searching engine. So, I'm looking forward to get your offers. Murat
