Dear Sir,
I am currently living in Garmisch-Partenkirchen, Germany. As my profile states, I am an expert in government contracts, however I believe that my skills may still be of use to you. I understand you are having problems making contact. My first goal of course would be to establish contact with a sales representative there. I don't believe that should be a problem.
If I cannot reach someone through the phone, I belong to a professional networking group that should provide the necessary methods to reach someone there. If that doesn't work, then I have a friend that lives in Koln which could stop by their offices.
As long as we can establish contact, I believe there should be no problem in putting together a proposal. I am an expert in this field. Although I don't have any reviews on Freelancer.com, I can provide a reference of a company in Russia that I worked with.
Lastly, I realize that you will not release funds unless proposal is accepted. However I propose that I be paid $100.00 after establishing contact with the company, and we get into the proposal building phase. The rest can be released only if your proposal is accepted. Would this work?
