Yep - they have a winch. They also can jack up the rear set of wheels so you can tow empty on just 2 wheels and the total weight of the trailer is under 400kgs so you can move the things around empty with one hand!
It's eventually going to go under the name PMC (Precious Metal Carriers) - but for now give the guy a call on 0418 373 938 (Matt Close) and let him know I pointed you in his direction and he will look after you. Matt is obviously a Targa competitor so any of you guys coming over can chat to him directly there if you are interested.
