This project really requires two threads of research: market and business research and logo design. Logo design, including best practices, trends, and graphic design principles is information that can readily be found on the internet. The market research, in the real world,would be most easily found in databases like Barrons, Reference USA, Business Source Premier, which our high school library does not subscribe to. In college, you will have access to these excellent sources.
When searching your industry keep in mind your search terms and the various ways of describing that industry. For example, babysitting services would also fall under childcare. Cell phones could be searched under mobile phones, iphone, cellular phones, mobile phones, etc.
Do yourself a favor and get a county library card. Their databases can be found at slcl.org under research and then click on small business resources. https://www.slcl.org/content/small-business-resources
Under Analyze Competitors look at Mergent Intellect and under Determine Potential look at First Research.
