Searching for a Hostfamily ?!

Hello,
I am searching for a hostfamily who would take me for the rest of my exchange year, which will end at the beginning of june.
I am 17 years old and from Germany.
If somebody could give me an email address from a possible hostfamily who could take me or if you could take me I would be grateful for an email or an answer.
Maybe you now somebody in the USA where it would be possible or you also did an exchange year and have an idea.

If you need more information please let me know.
