What would you do … if a prospect had no clue?

I've been identifying red flags lately and collecting advice on what to do. Here's one I'd love to hear from you on, if this has happened to you, especially:


A prospect calls and says, “I just need a logo and a brochure. It’s a small project and won’t take long. Can I have a quick price?”

"No clue" doesn't mean they're bad people or would even be a bad client. It just means they need to be educated, without being patronizing, of course, which is going to cost more.

Has something like this happened to you? What else do they say that raises this red flag and betrays their ignorance? What did you do?
