Small trailer for rumbling – no caravan

Sorry, maybe it’s wrong here, but I can’t find a more suitable forum: We have to break down a large house and renovate it and then move in some time and then constantly care for the garden… So I want to buy a cheap trailer with which I can drive to the garbage dump or get a bag of cement from the hardware store etc. It would be pulled by a VW Bus T3 or an Omega 6 cylinder. It should be extremely cheap in the purchase and in the follow-up costs (so best unbraked?) and so handy that I can “place it” in front of my head at least with the help of a simple bottle train in the garage. What are the names of such trailers? What should I look for? What should I pay attention to? Thank you for tips to a clingy but so far hangless traffic participant….
