Yes there are plenty of schools that provide helicopter IR training.
But itīs gonna cost you! You can figure about $35.000.- for ab-initio IR. If you already have have FAA IR then there is some reduction but still lot of theory and about 10 hrs training+checkride.
Instrument training in Europe can only be done on IFR certified helicopters like B206 w/scas, AS355 and so on, so instrument training in R-22 or H-300 is no longer available.
