Design a portable display stand banner

Information for the business: we provide chiropractic care for humans and animals
Industry: Healthcare
Design details: We are exhibiting at the London Vet Show on 19/20 November and are buying a new fabric exhibition stand. We need someone to design the picture to go on the stand, using wording and photographs we have already chosen.
This is what we are planning to buy : http://www.printdesigns.com/fabric-exhibition-stands/498-texstyle-fabric-rectangle-bundle-100-off.html
Target audience: Vets and other veterinary professionals. Patients.
Ideas for the visual style: Bright, engaging but not too 'wacky'!
Things to avoid: Cutesy animals, cartoons, medical, white coats
Preferred colors: Blue, green, red
Where the design will be used: fabric exhibition stand
Extra notes: We have had a go (as per attached files). We own the small photos but not the background ones, although we may be able to get permission. Would be best if we can have files without needing to get copyright etc. We would like a couple of different designs to choose from.
Working to a deadline. Need artwork by Thursday 5th November, absolute latest.
