Product Comparison application for an Online Store on Shopify

I am looking to have a customized list of features/specifications unique to each product (approx. 50) pulled to a specifications tab on the product page. Then have a product comparison application for shoppers to compare up to 5 products side by side like "apples to apples" based on the list of 50 features/specifications. My store is on Shopify. The Product Compare app they have available was not detailed enough so I am looking for a developer to create an alternative that will work for my products. .
