I don't know about english clubs and Workshops in Limburg. But I think a some of the dutch Nikonians speak english too.
I can't get much info from your profile and image gallery, but maybe you can shoot with one of more Nikonians together. I'm living nearby Rotterdam. That's about 2 hours drive from the south of Limburg. In the middle it's only one hour
Maybe not exactly what you are looking for but it can be fun. And Nikonians is like a 'club' too.
