[Closed] 10' x 8" metal storage shed for School PTA - budget £1k - recommendations?

The PTA at my kids school need to buy a new storage shed.
needs to be approx. 10' x 8' and will be used to store kit for events.
They've had problems with rodents/squirrels in the past and feel a metal shed would be more robust and require less maintenance.
Security not a massive issue, ability to fit a decent padlock will suffice.
Current rotten wooden shed sitting on a few paving slabs, so no base to speak of.
Budget is £1k, including a base - any ideas or recommendations??
There will be a few people around to help assemble it, so flat pack OK.
