At those prices you mention for the equipment it's obvious that material cost for a homebrew project will probably be higher.
Only is it impossible to find such equipment in Switzerland at those prices, here all you usually get is the professional equipment at professional prices. So you'd pay more for the crane alone than you paid for all your equipment. And finding used equipment is like looking for a needle in a haystack. The fact is that there are just not enough car enthusiasts who do everything themselves and need such equipment over here.
