Telus Box wrapping

Hello! I am in Sechelt, British Columbia, and on the Board of Directors of a local charity. There is a Telus box in front of our building and we are interested in having it vinyl wrapped. We would have a design contest among our members, and we would cover the cost of the wrap. We would sending the design to Telus for approval before proceeding. Who can I contact at Telus for permission to start the process.
