Hi, I have previous experience with recording (you can check my profile) and I already checked your text - should not be a problem. I can start right now and send you both files in mp3 in one hour. I'm native czech so there is absolutely no problem with that czech part and about that german text - I learned german language during my high school studies for 7 years, so there should not be a problem to read it and record it as well. If you're interested, please let me know. Looking forward!
Lukas
