Character Design for Self-Storage

I need someone to help me develop a character for a new self storage brand. The principle brand name is "Easy", with each location adopting a subsidiary brand. The first location will be called "Westside Easy". I want a character that will sit with the brand which explains what we offer, is fun and approachable, and conveys good value for money. Current front-runner is a "box" character. However, we could investigate having a cast of characters (for example, a lock, box and a pickup truck/ ute). Character will appear wherever the brand does: on the facility, on LED signage which will be used to celebrate things happening in the local community, wayfinding in the facility, on local community sports team jerseys etc.
