Looking for 2w exchange or homestay for 15y old female into an English speaking country

Hello.
We are looking for 2w exchange or homestay for our 15y old daughter into an English speaking country

Our youngest daughter will turn 15 in fall and is looking for an 2w exchange or homestay with an English speaking family in fall 2015 during school time.
Ideally into a family with a daughter of about the same age, who’d like to visit Germany in an exchange visit. But also ok if there is no reciprocation. Best timing would be 10/17 to 11/1/2015 - visiting secondary school during that time to maximize language and culture exposure.

Our daughter visits 10th grade of a German highschool with English lessons since 6th grade. She’s doing well, but since she would like to take English as advanced course for graduation, she would like to strengthen her English skills and get some experience abroad.

She is a nice person from a nonsmoker family, sportive (basketball), likes animals and reading a lot and plays the violine. We have two other kids (20 female – studying away at university, 18 male – graduating, living with us). We are living in Liederbach, 20km from Frankfurt/M.
Naturally all expenses would be paid by us, or whatever reciprocation we agree.

Kind Regards
Arnd Merlevede
