I have a very similar problem than you concerning language (my first language being french) I had some problem traducting hypnotic scripts in the short time, but in the long term I actually realised that those scripts are really just useless, when you get further in your learnings you will find instant inductions which use very little script. Of course you have to say them but there is no problem if it's not exactly the same in Dutch.
Hypnosis really works with your presence and your normal hability to influence someone, just make them believe you can hypnotise someone and you can do it by waving a banana in front of their eyes.
I actually see no problem in mixing mentalism and magic together, there are some very sucessful performers which have been using both in the same time here is an example;

I can recommend you a very good book called ''reality is plastic by Anthony Jaquins'' he hand ship them so just google him and you will find his website.
Other good material would be Richard nongard DVD's and more importantly Ormond Mc.Gill Encyclopedia of stage hypnosis.
