Design 3 x polo-shirt crests (Adobe Illustrator)

Design 3 crests in Adobe illustrator. The designs are for embroidering onto polo-shirt chests (approx 8x8cm).

The brand name is "BENTLEY". Other key trademark words are "Est 1962" and "British Sporting Heritage".

Visually, the designs should reflect sport. One design should reflect rugby; one design should reflect cricket; and the final design should reflect tennis. All designs must include the British flag, the "B", and a crown. Two pdf designs are attached that help to illustrate the "B", crown, and flag.

Examples of the style design I am looking for are:
