I can not recommend you to book this "expert" at all. Very unprofessional. I want to stress that you can neither rely on the prices on his website, nor on the prices you will be told from his secretary in the office. You will get a call shortly before the meeting and he will raise the price by more than 100 Euro without any explanation. Asking him why he would want to have a higher price, he will give you no reason. Again, this is very unprofessional. Do not book this "expert", it is SCAM.
