ey mark, if i should bet on names who are big here in cz, i would deffinitely take:
The Advent, DJ Rush, Adam Beyer, Dave Clarke, Ben Sims, Surgeon, Speedy J, Chris Liebing, Green Velvet, Luke Slater, Umek, Green Velvet, etc...

then I would combine with some names like Mulero, Bas Mooy, Radial, Wittekind/Natus, Dj Ogi, Rumenige/Loktibrada, Dj Boss or stuff like that.

depends on how big is your budget,ofcourse.
