European languages required for recording.

I have a recording project for European people. I need a few recorders from Europe. French, German, Slovakian, and Polish people can record the recording. The recording will be on your mobile through an app. The timeline for this project is 3 days, strictly follow the timeline. Knowledge of English is a must.
Record 500 sentences on your mobile through an app.
Duration 1.5 hours.
Thanks
