Kia Ora. Congrats on pivoting your business and a creative outcome.
Have a look at website building platforms like SquareSpace or Weebly, plus you don’t have to make a long term commitment. Should be less expensive than what you have been quoted.
I’ve just come across a site called Needed.co.nz that has a list of creative contractors for smaller projects. No personal experience with it, but may be worth a look.
