#8 & 9 are a little too intricate for what we're looking for, however #29 does have a nice look. Do you think there is a way you could style the outside circular frame a bit more (check the attachments for some inspiration) and maybe try out a couple different typefaces?
Working with our client, she likes the circular design and what you've done in the latest interations, but the CM font isn't really speaking to her. Could you try some other variations?
