Startup Idea: Sales Comparison Tool Development

Startup idea to develop a system that aids sales professionals in comparing their products with competitors'. The tool should be able to crawl across various products, detect changes and updates, and distribute this information effortlessly to customers.

I work in sales. The biggest problem I have is trying to compare (easily) for my product in comparison to other vendors. I would like a system that allows me to update developments and changes in the various products, and then have it easily distributed to customers. Ideally this kind of tool would "crawl" across my products as well as that of competitors to harvest the respective information. I would pay a monthly subscription fee of up to $50 for a correct product. No.
