I think it would be a good idea to use the 2,5 years to make transition to the Netherlands..
(residence permit, work permit, application for the language school)
I know you want to leave as soon as possible, but you should not be too impulsive...
After all, once you are in the Netherlands, you can't go back simply..
You need to sort everything out..
And this will take a long time
I am not an expert...
But I think this is the most sensible thing to do
