This is all great to write down as to what it could eventually become.. I think it has to be chunked to more manageable units, first. I mean, whether you have the individual skills required or not, it'll start by requesting a page and inevitably forgetting to show the respect Unicode deserves. That's what I'm doing to learn. - See how a page is structured (does it use schema.org's stuff?). Its fields, URL pattern, sitemap, resource urls, selectors, etc. - Fetch a page. - Parse it and extract data. - Save data. - Rinse, repeat. I'm also learning about D3 and many cool things.

In a gold rush, people who sell shovels make a good living. You probably want to make something that helps with decision making or triggers buying according to price (from your description).
