Keter factor 6x6 shed installation service

I have ordered the Keter Factor 6x6 shed, which needs to be installed at the bottom of our garden. We have concrete slabs (the larger, paving type of slabs) for the base, but apparently it also comes with a base of sorts. Please have a look at the specs of this shed to make sure you are familiar with it before the time. (it's just a plastic shed, so not really rocket science...but I don't have the time or the patience to do it myself) Anyways, we need this shed put up, and you will need to have all the tools for the job (an electric screwdriver is apparently essential), and may also have to move the slabs (each is liftable by me alone) into position for a neat fit, which will also be level. This is price-work and not by the hour, and so please quote accordingly. (we have loads of other small little jobs around the house that can be charged by the hour, but this is not one of them) The address is UB3 we need the job as soon as possible. Thanks Sharan
