Does anyone have experience with Immagine New Zealand immigration advisors, previously known as Protea Pacific?

This is their site, if I can post it here; New Zealand Immigration Specialists: IMMagine New Zealand Immigration: Emigrate to New Zealand,Migrate to New Zealand
(not advertising!)

Please let me know, good or bad experiences, their way of working, etc.
We are considering to use them for a work visa application.

Cheers,
