Complete New user buying second hand setup.

I live in a country town in Western Australia. My goal is to have a reef
tank and I thought I would research the subject as much as possible for a
couple of years before fulfilling my dream. But ...

someone locally is selling a COMPLETE system for A$2000. Included in the
price is live coral, lighting, protein skimmer, filtration system, heater,
wave maker, fish, stand and canopy. The size is (metric) 120 x 60 x 60
which is 48x24x24 inches. Does this sound like a fair and reasonable price?

Considering I am a COMPLETE novice do you recommend I go ahead and purchase
this system and learn as much as I can from the current owner and continue
to learn along the way as I go or to continue on my path of researching and
learning prior to spending any money?

I thought if I went ahead with the purchase that I would only go through
with it if the current owner was willing to set the system up for me in my
own home so I wouldn't do any damage or transport it wrongly.

Thanks in advance for any/all suggestions.
