Poster for Soccer/Futbol Yard Sign

I am looking to work with a talented, practical graphic designer to create a poster to help promote awareness and registrations for our soccer (futbol) league (http://ayso45.org). This poster will be shared in front yards, sidewalks and public spaces all around town.

- Style: The aesthetic of the poster should be clear, family friendly and fun.
- Colors: The primary colors should be red and blue (the AYSO colors). The background can be anything as long as it is easy to read and understand
- Feel of the Poster: The poster should exude an positive energy that would attract parents to register their children (ages 5-18)

Ideal skills and experience:
- Excellent graphic design skills
- Proven experience in creating promotional posters for distributing around town
- Portfolio showcasing family-friendly/community design styles
- Expertise in keeping it simple, yet distinctive
- Adobe Creative Cloud proficiency, particularly Photoshop and Illustrator

Attached are some examples:
- i9sports - a local competitor
- Wheels - a fun example from another sport
- AYSO Street Banner - currently in use
- AYSO Yard sign (red and blue) - I would like something better than this
- AYSO - an old online image
