If you want to make money from It then you really need to take your site more seriously. Weather that means throwing money at it or putting in that leg work :)

This is really about SEO. Google may penalise you if you just repeat all the product stats over and over again on a single page, but if you change the way that content is formatted, your page may rank higher for those keywords.

Wordsmith from Automated Insights would suit your needs very well. It allows you to automatically generate site-ready product descriptions from product data. Pricing is based on volume, and product descriptions generaly start at $0.20. Edmunds.com uses it to generate copy for their car descriptions. Here are a bunch of examples (select any car from the list on this page).
You can learn more about Wordsmith at https://automatedinsights.com/solutions/#e-commerce. And you can get a demo here as well.

All the best!
