Dex not a bad suggestion but it may not be so simple or cheap.
Cranes in my experiance charge from depot and return with 2 hour minimum.
it may only be 150 kg but you need a lot of reach to get over the house and if there is power line in the way even more so.
Could work out needing a fairly big crane and setting up would take at least 1/2 hour and same to pack up.
