Hi There,
Were a New Zealand Based Design Company that's all about Quality and Classy designs, although we are a relatively new company we have a range of different websites that have been completed and live.
What you are requesting in the details sounds like a suitable candidate for a Joomla based website.
We have created many websites using the Joomla platform and find it great to work with, and once the site is complete Joomla has a built in backend/administrator section so that you (the client) can change page details, images and content with ease all online.
Please see the message i sent with examples of websites we've created.
Kind regards
