Hi - as a photographer/videographer I've worked with a few different real estate agents and still find it hard to put a finger on whether they're working hard or not... I believe that the photos/videos do 90% of the work for them (well, I would wouldn't I....!!).
I've helped with about 5 house transactions in Wellington that have been private sale and all have been smooth with very quick sales. A good listing on TradeMe Property will have lots of eyes on it within hours and if you've sold a car in the past you should be fine with selling your house (I've done it myself a couple of times).
There are a few real estate videos on my website... it seems that a lot of people who are disheartened with overly Photoshopped still photos are a lot more trusting of videos now, and it means people see your house at it's best (saves faffing around with open homes - you show people around on your terms & times that suit).
I'm just about to start offering a photo/video service to Wellington region people who are keen to have a crack at selling their homes privately.
