Hey Tom,
First of all, I only use the language Dutch on my website, so not both Dutch as English.
If you also want this you can follow this steps:
When you have bought WPML (wpml.org) and installed all plugins you can import the files via FTP in the following folders:
1) the en_NL files:
wp content > themes > neighborhood > languages
2) woocommerce files:
wp content > plugins > woocommerce > i18n > languages
Once you have uploaded the files you go to your backend:
WPML > Theme and plugins localization > language locale settings
Change the locale file name of the language English to: en_NL.mo
Done! Good luck mate
