For paid employment, you need to apply for a single permit~ A single permit combines both the residence permit as well as the work permit..
For most purposes of stay you have to meet certain income requirements.
You have to show you have sufficient long-term means of support for at least 12 months at the start of the procedure.
And yes, the application also costs money.. But I don't know the exact amount~
The fees vary per category/ purpose of stay..
I have also found the website of the Representative Office of The Netherlands (located in Taipei)..
I think you can also ask for information here about the application and the visa for the Netherlands~
