Well,

This site is mostly about the technical side of moving, and this question is probably out of our scope.

I would suggest you to look for some forums dealing with immigration to Germany, and this way you will also get to know some other people with problems and issues similar to yours.

For example, here is one page on EscapeArtist.com that lists forums and many other valuable resources you could check dealing with moving to Germany: http://www.escapeartist.com/germany/expatriates.htm 

Also, if you decide to move and want to check prices of the moving service you could you our form to get quotes from companies that organize shipping from America to Germany.
