I like the use of color and overall clear design of the first and second logos; however, the main focus of the logo needs to be "The Power of More" with no reference to BrightStar. Keep in mind that the logo is for a conference with the theme of "The Power of More" so that needs to be the main feature. We are hosting the conference in Nashville, and it's for clinical staff (nurses), salespeople and directors of operations so if that can be conveyed somehow, that would be wonderful. Please reference the attachment I included in my initial posting of previous conference logos to get a better idea of what I'm looking for.
Looking forward to seeing what you can come up with. Thanks!
