Your client doesn't know what they want, and they don't know what any of the things you mean ask.

You know the industry that the client works in, you know the name.

Throw together a few different ideas in very rough draft.

Send them to the client making very clear that these are rough sketches to get a concept not a final piece and ask them to rate each one by how much they like them and give feedback.

Iterate on the feedback.

I'm a software engineer not graphic designer but over and over again I find that if you ask someone what they want they don't know. If you present them with a few options though they will immediately know they don't want 1 or 3 but they sort of like 2 but can you add this bit from 4 and maybe X and sometimes a bit of U and then add a unicorn.
