Startup Idea: Product Finder for Small Business

Startup idea to develop a software that assists small business owners in locating profitable items with low overhead and reduced shipping costs. This software will categorize these products and provide information on where they can be sourced affordably.

I do have small business. I am always looking for items, which can sell most with little overhead and less shipping. I want software to find for me, which things I can find and where. I want to use such software which categorizes the products and where they can be found with cheap prices.
