ArabMark Team (http://www.arabmark.com) would like to market our
services in Germany & Austria. How can we achieve this? What are the
methods that we shall follow?

I doubt if you will get a comprehensive answer at hthe current

research work to be done.
May I point your attention to the google answers pricing guidelines to
find out more ?
