This sounds like an interesting venture.
Complete disclosure, this is my husband’s business DAVO.NZ.
They are supportive of supporting small business New Zealand (being a small business themselves). Have a chat with Dave on 021 373 410..
Alternatively, you can tap into talent at fiverr.com for help with the digital assets you are looking for.
Don’t forget about including linkedin and Facebook in your go to market strategy (so think about the right messaging and creative for use in these channels).
All the best!
