There is a lot of help available from the Kamer van Koophandle but the best advice I've found, in English, came from the Womens Business Initiative International based in Den Haag. They have lots of networking events and workshops on how to start your business and how to move it forward. It has been really positive for a number of people and I recommend that you check that out. There is a website www.womensbusinessintitative.net.
