Gordon Handy Machinery Kaikoura - New Zealand

What are the ins and outs of having you sell my tractor for me on behalf, i have a new holland tl80a rops tractor that is currently being leased at waikene station inland rd, i own it with a post driver that i used for fencing while i lived in kaikoura, i have since moved away and no longer require it. i have had a valuation done by norwood chch, which came back as @ $30,000incl if i were to sell it privately, however if you were to try and sell it on behalf i would like your appraisel on value, terry franicevic has been doing services and maintenance on the tractor for the last 2 years.
