metal shed (Puckeridge SG11)

This metal shed is quite old and needs a very good clean and some tlc. The dimensions are: 170cm wide, 80cm deep, 166cm high at the outer edges, 180cm high at the apex. It has slight dents in some places. I've tried to show these in the photos. There are two doors, which should slide, however, they've not been on for some time, so I'm not sure if the sliding mechanism still works. The ridge that they slide along is slightly bent at the top and there a a couple of areas where the edges of the doors are bent.
There's slight rust on the top, front of the shed and more rust on the outside of the roof, though I think it's largely cosmetic. We would like to have the shed taken whole, so you'd need a large van to transport it. If you don't have a van, I'm willing to have a go at dismantling it, however, I'm not sure how easy this would be, or whether it would even be possible.
