Well, you can't fly VFR without charts, so go IFR. Damn sight easier too.
As an afterthought, do a search for Turkish flying clubs and e-mail a few to ask re VFR procedures. charts etc. They'd be a darn sight more helpful than the government agencies, and a lot better informed.
You're beginning to discover the nightmare of Turkish bureaucracy. Also most, if no all official documents will be in Turkish only. Do you read Turkish?
Silly me. What you really want is the TPC series, Tactical Pilotage Charts. Half Mil scale, 1/4 Mil JOG would cost a fortune on that route. You'll still need to do some amendments from AIP's I expect to ensure all restricted airspace really is depicted.
Links to Stanfords TPC catalogue, and one in USA. They're in stock, too!
