It maybe helps, if you state your starting/returning point in Germany - since it makes a big difference, where you wil come from.

Please be specific, since e.g. if you say Frankfurt - you could be close to Hahn, where you can pick up a Ryan air flight - if you are in the other direction in Frankfurt, transport just to Hahn could cost you more than it is worth.
