Installing 2nd hand heatpump

We have an opportunity to get a 4 year old 3.5kw Panasonic heat pump which has been professionally removed but before we get it we are wanting to know install costs. I don't have photos atm but it is a back to back installation on a weatherboard house. Less than 5m from installation location to the switch board which has recently been replaced, very easy access with large roof space. I will have a small concrete pad for the outdoor unit before installation. Might not be enough info to get a quote for but even a price range would be great. Thanks
