Charity javascript game development

As part of our UK-wide campaign in May 2014, I am looking for an experienced Javascript professional to develop a simple web-based game for the charity I work for by the end of March 2013.

The game will involve users choosing eight images from a selection of 16 images which are coded as either "yes" or "no". Once eight have been selected, the user can then click a "submit" button which will calculate their score.

All images and design will be provided, just the coding and the support required.

A simplified pdf visual is included.

Thanks
