There are couple studios in Prague directly or in distance up to 20 kilometres but as stated there i would personally recommend MaDalton from Brno, it is about 200 km from Prague (but on the way to Budapest), he is fair and very experienced.
But depends on what you need, mail me to man.from.prague at seznam.cz if i can help you anyhow.
