Transportation of a massive shed

Hi, 

I'm looking for advice and suggestions about how to transport a dismantled but still massive shed locally within Haringey.

The biggest section is the roof which measures 283 X 280 X 9 cm.

There are then the four side panels which are a maximum of 275 X 190 cm and the base which is 275 X 273 cm.

Two guys with a Luton van tried at the weekend but the roof was too big for the shutter door.

I'm thinking either a flatbed van or a glass transportation van (which have those panels on the outside for big bits of glass). Does anyone know anyone who does man and van services with those sorts of vehicles?

Or any other suggestions welcome.

Thanks
