$700 · WANTED - Commercial Storage Option

I am in need of a 600 to 1000 square foot (at least 10 foot high) storage option for commercial storage purposes. A solution needs to be dry, secure and have a concrete floor. Also, the storage facility needs to be able to accommodate 53-foot trailers which are used to offload equipment. We are looking for a long-term solution, as we work off the Island, and currently, our storage is on the mainland. We would spend minimal time at the facility (every few months) and occasionally to do maintenance on our equipment. A facility near the airport, by Wilkinson Jail, Sydney or Saanich is preferable but not a deal-breaker. Thank you
