If you are thinking of Hours Building in the USA I would strongly recommend LA Helicopters in Long Beach California.
I have been there twice last year and going back in March
Take advantage of the exchange rate and fly around Sunny California!!!!!
$170 per hour solo R22 with a discount for block hours
Good ships and very good team of staff
No Visa required for hours building
Convert your JAR licence before you go and then just a school checkout required with the CFI a frenchman called Guill.(a top bloke)
If you would like any other info please PM me
