As KayaKoyuOldBoy has said you are not likely to succeed with your plan as it stands I am afraid!
We too wanted to do a "self-drive" option. We had quotes for moving our stuff of £8,500 and more! I spoke with some very good friends in Turkey who have relatives in the import/export world with particular experience of the borders near istanbul and got this response about driving our own stuff in ...
O... and his colleague A... called me today. Here are some notes: they can make sure you pass through Customs smoothly and quickly. the Customs you need to go through is called Ipsala (on the border with Greece) he expects the total cost of getting your stuff through is 2000 - 2500 euros. ... (that is also assuming you can actually convince the Customs to let your stuff in!)
... He also added it's much cheaper if these goods were coming in a container or in a transportation company truck. He mentioned about 500 euros.I was also going to buy a 7.5T box lorry off eBay and drive it one way. The hire companies will not grant you insurance for Turkey. I even asked my own insurance broker if they would do part insurance. They wouldn't touch it! So was going down "buy a cheap van and nurse it there" route! Could get the requisite insurance then. I had even mapped that the route down through Italy to Brindisi the by ferry to Igoumenitsa in Greece then drive to ipsala and cross into Turkey was the most cost effective. Then drive the van back to Customs at izmir and dump it! (6 month import rule) It worked out cheaper than hiring. This approach gave us advantages over shipping in that we had some storage at the other end (the van!) so we had flexibility in the plan!
The killer was the Turkish Customs!
Anyway to cut a long story short we have gone to John Willard at Freightbrain International (
http://www.freightbrain.co.uk/) he in association with Ozcan Soyer in Turkey certainly seem to have real experience in getting these types of problems sorted quite easily. John is also very flexible in the way you actually do your move - he will actually listen to you and advise you! Also I know others in this forum have used him and had excellent experiences! Also he is reasonably priced!
As for pets - we are bringing out our 2 cats (I know they're not as big as a Great Dane!) But you need to be careful if you fly your dog! Some airlines (I know than Onur is one but there may be others) will quite happily accept your money for your pet to go into the hold but not tell you that it isn't pressurised! Then when it comes to boarding they would tell you that the animal was not fit to travel and keep your money! But there are airlines that will allow you to take them in the cabin - although don't know if a Great Dane would be allowed. But you could of course drive it with the dog in a car. The route I was going to use is about 3,500 miles one-way.
Anyway I wish you well in your quest!
We will be moving "lock, stock and barrell" in a few weeks so will give an update when it's all done and dusted!
Best wishes
