Advice for putting my small business on Facebook?

[Berry]

I own a very small local business and I want to boost recognition by creating a Facebook account. I need as much advice as I can possibly get though, so any feedback you can give me is so greatly appreciated. I do not want to have to pay for any services -- Facebook is free anyway, right? I'm looking forward to any tips and suggestions you can offer. Thanks!
I know what I want to post and such, but how can I reach out to other Facebook users? How do I gain the recognition?
James, thanks so much. I noticed that apparently my business does have a facebook page, that I did not create. There is a link that says "Is this your business?" Should I revamp that page or create my own new one? What do I do?
