Get someone to fabricate a trolley which is effectively two upturned isoceles triangles with a chequer plate deck fastened to the underside of the triangles and an axle at the apex the deck should engage on the upper step and shallow the angle down, if too steep add a further section which hinges and folds back on the deck so taking up no more space. I would budget £500 to get it fabricated but you may find something you can adapt if budget is an issue. This approcah allows you to keep it round the back and wheel it out when needed (make sure no wider than your garden gate)
