Design a front & back cover for a safety products catalogue (outside cover only)

Design details: We require a front and back cover (outside only), including spine, for a safety products catalogue. The catalogue contains safety signs, fire safety equipment, PPE etc. The cover will be branded with our corporate identity and logo, complete with our contact details. Logo and contact details will be provided.
The catalogue is provided by our supplier, hence we only need the cover designing. Dimensions of the cover will be 425 x 297mm to allow space for the spine, plus a 4mm bleed.
We will require delivery of the editable files, as well as a hi-res PDF file with fonts embedded.
Content on the front/back side and body: Logo, photos, contact details. (No faces)
Ideas for the visual style: Needs to tie in to our main company catalogue style. This will be provided.
