How to get a logo for a small business?

Hello, I'm interested in understanding the process of acquiring a logo for a small business. Could you elaborate on the steps involved? I'm particularly curious about the design process, whether it's best to hire a professional designer or use an online tool, and what factors should be considered in choosing a logo. Additionally, I'd like to know about the cost implications and any legal considerations that might arise during this process. Could you provide me with a concise overview of how to get a logo for a small business, from start to finish? Thank you for your time and expertise in this matter.
