I need an artist to draw a garland, comprising the national symbols of 27 countries

Information for the business: World War One Charity
Design details: I need a garland comprising national symbols of 27 different countries.

Each of the countries has a range of symbols associated with it. For example if you Google 'national symbols of China' you will find the following:

Animal: Chinese Dragon, Giant Panda.
Bird: Red-crowned Crane, Golden Pheasant.
Coat of Arms:
Coat of Arms: China's national emblem is composed of the entrance gate to the Forbidden City in Beijing, with five stars above it representing the Communist Party of China and the four social classes. ...
Flag of China.
Fruit: Kiwi.

I would prefer the garland to be created using national flora (flowers, fruit, or trees) where possible, or birds, or animals (in that order). This job requires that you research the national symbols of each country (by means of a simple Google search), and choose which to use for each country in discussion with me, then redrawing each element before integrating them all to create the finished garland.

The garland should be circular, colourful, leafy and constructed on a base of a barbed wire circle.
Target audience: WW1 veterans
Ideas for the visual style: Please see attached images for ideas.
Extra notes: This design must be supplied as a CMYK vector, with each element on a separate layer.
