I need 2 posters designed for a veterinary emergency room and ICU

I need 2 posters that include text (but not necessarily any of the layout or design) that I will provide and that will be suitable for printing as A3 laminates. The posters will be stuck on a white wall with a relatively large amount of space around the posters.

The content provides guidance and direction to veterinary surgeons and nurses working in a busy veterinary emergency room and an ICU (critical patients):

The final design for the ER poster should convey quiet calm, focus and order. Tranquility. Organising the chaos.

The final design for the 'critical patients' poster should convey calm efficiency and purposefulness. Making things happen.

The styles should be modern, professional, not too colourful, ideally with a medical/veterinary theme.

Target audience is veterinary surgeons, nurses, and students, both genders, aged 21-40 years old.

Ideally start and deliver as soon as possible but some flexibility possible.
