Hello ,
I have this kind of job for Austrian companies , in German language.
Actually my experience is that very often on the website was no info about CEO and CFO , then I was searching in Xing and Linkedin , there is possible very often to find the person , but if you want contact details you should have paid profile.
My client find also very efficient when I list the phone number of the company and the e-mail and after that when you contact the company you can ask about the Person which I found in Xing.
I am ready to do test work before you hire me , let say 30 min and after that you can decide if you want to work with me.
regards
Greta Maslenishka
