Need stable server. Most of my clients are located in Europe.

The best servers in Europe are available from hostround.com and hostsailor.com.
Their goal is to provide quality infrastructure hosting in world-class data facilities, at a cost accessible to enterprises, any businesses, and end-users alike.

I recommend Zakservers.com offshore dedicated servers all the time and would recommend them above any other hosting provider I have dealt with. One of their highest priorities is to provide state of the art security for customer's data.
