I need a Shopify designer

Our business name is Rescue Nation. We are an apparel ecommerce. A portion of each item sold will be donated to a no kill animal shelter. We pick a new shelter every quarter (every 3 months). The most important features on the site, will be a timer and a counter so the customer will be able to see their donation added to the amount in real time the moment they check out, and the timer will show how much time is left of the 3 month period. Id like the site to be simple, fun, and user friendly.
