Here is a logotype I have come up with for my wife’s public relations business. She caters towards fashion clients, but also works with other industries. She wanted to avoid the look a lot of fashion pr firms have (a lot of Bodoni/Didot, or Futura, or on the other end, distressed fonts for edgier clients). She likes clean lines, likes Art Deco, wanted something gender neutral—not too girly. No sharp lines, as she read in a Feng Shui book that those are bad.
The name is “son public relations.” SON stands for “Something Out of Nothing” because our last name is Nix, which in Dutch (along with a few other languages, but my family is from Holland, so it’s Dutch in this case) means “nothing.” So her clients are literally getting something out of nothing.
By the way, I already pointed out to her that Something Out Of Nothing should be SOON, not SON. But she liked SON. Since I want to remain happily married, I let it go.
After a couple of tries, we settled on Estilo Script. Clean, Deco-inspired, curvy without being too feminine, and no sharp lines—rounded terminals even!

Any comments? She expressly did not want a logo, just a logotype. Also, any suggestions for a companion serif face? I was thinking a modern, but didn’t want something with so much contrast.

Here are some further concepts taking into account some of your concepts. I have layed them out on a 3.5x2 business card format to get a better perspective. I’m still not feeling the swash, and as much as I feel like I’m copping out of designing the logo, I like the way it looks “straight out of the box” on the bottom 2 samples.
