Mural @ The Sheds

I need a voting mechanism designed for our website so that the public can vote on their favorite artwork for a shed wall we're painting. There would be 4 artworks and we want the public to decide which one they'd love. We need the work completed by Friday 21 October.

Our website is:
www.theshedsatbrendale.com

The voting mechanism would go here:

Thank you
