yard area wanted - south Warwickshire

We are looking for a yard to rent in preferably south Warwickshire. We are looking to site up to three 40ft shipping containers with vehicular access. The ideal criteria is that we would be able to site the three containers at least 30m away from any buildings (although lesser distances could be of interest to us). Whilst we do not require exclusive use of the yard no other storage units would be able to be in the designated area or any vehicles parked in the area (inc caravans). Any on-site security i.e cctv would be a bonus but is not a requirement. The containers would be storing 1.4G fireworks (ordinary domestic fireworks) and hence the requirements for the distances from buildings. The containers we have are fitted with their own low voltage alarm systems.
