If you have been to Europe before then I would say better plan on your own. Since the public transport is really good in Europe. Whenever I have traveled to Europe I have stayed in Hostels. So my take on expense for turkey would be around less than 1 lakh for solo person with Return Flight.
Plan your trip on your own.. check out @wanderleen on instagram..she is a traveller and she is the wife of auditya venkatesh ( india's prominent photographer ) they both went for a trip to turkey just a couple of days back..
You know your interests better than the tour operators. Identify your interests and match the places in Turkey. Turkey has everything from beaches to mountains, history to modern stuff. I would suggest to plan your trip yourself. Indigo has started direct flights to Istanbul which would be cost effective for you. Round trip was starting at 30 K. You get good hotels at affordable prices in Istanbul. You should be able to complete the trip at 1-1.25 Lakhs (Home to Home) with full experience of Turkey.
