As far as I know Rabobank is still the most hostile towards bitcoin.
You should have less problems with ING and or ABN AMRO, however this could change any day.
You can use
https://bitonic.nl/ with Ideal or
https://www.clevercoin.com/nl with other payment methods, or use
https://localbitcoins.com/ for a cash solution.
We also have
https://www.happycoins.com/nl and
https://anycoindirect.eu/ which are all serious companies.
If you want "Fresh" bitcoins you can have a look at our Mint:
https://www.blocktrail.com/mint/We accept only bitcoin at this time though.
If you want to start a bitcoin company, I suggest you contact the
https://bitcoinembassy.nl/ or
http://stichtingbitcoin.nl/. If you want to exchange bitcoin for FIAT at your compnay I suggest you contact "de Nederlandse verenigde bitcoinbedrijven. Can't find the info though.
Best Regards,
