Does anyone know a cheap way to transport stuff from Prague to Turkey?

Hi! I'm leaving Prague and moving to Turkey...I have some things that need to be transported to Turkey (Izmir) and need to find a cheaper solution. The currier companies have quoted at least 25,000Kc for the move. I will be checking other options, plus asking you! I leave on Wednesday next week (30th Aug) and if any of you have any ideas it would be great to hear them!! The airlines only allow 20kg, and I have a bit more than that...computer, guitar, etc...anyway, any help would be much appreciated!
