Phone numbers database for Germany needed

I need a telephone directory of german people (i hope it's possible). fields required: *name (most important) *last name (most important) *middle name (most important) *phone number *address (more fields are appreciated) Variant A: you can send me electronic database., say mysql, excel, txt etc.. Variant B: you can tell me where i can get the base: where i can buy CD or book or smth like that online. Variant C: you can refer me to the official department which may provide that information and help me get the base from them. Sure, i'll pay highest price for the (A) variant. ps: if you can somehow get more extended (more fields) database, it would be perfect and i'm ready to discuss that separately. regards, Alex
