The biggest in NL is the Amstel Gold sportief. For 2012, you have to enter a lottery to get a place - entry to the lottery finishes 10 Oct 2011, I think.
Others in NL seem to be named after ex-pros. Steven Rooks and Michael Boogerd have annual events (easy to find with google), usually in the south of NL using parts of the Amstel Gold and L-B-L routes.
Any sportief in the south will likely involve a reasonable amount of climbing. Not exactly the alps - more of the short, sharp, shock variety.
