Changing price of the private detective services

Questin: What is – we have agreed on a price, and the detective asks additional money to fulfill the order or after it?
Answer: This is normal. Detectives are not clairvoyants – services market here is very subjective and to determine the price of the course is possible only on a very routine orders – which occur every day. But if the agency has undertaken, for example for the search, the exact price then no one will say – the amount may be increased, but it can also decrease – because along the way opened additional details, or vice versa difficulties – all is solved easier than you think. What would you do on the site investigator, had begun to search in one of the cities in China, and it would end up in the United States in Alaska? Of course, we have to raise the price, tariffs in overseas colleagues not an example of Ukrainian.
