do you know a nice provider

Personally I'm using a VPS (for about two years now) of one of the big providers in Germany, and I can say that all in all I'm very satisfied. (I can't say much about the quality of their support, though, in case you'd want a human being at the other end — I've so far never had the need.)  Performance-wise, even the smallest option would seem more than sufficient for what you're planning to realize...
