#6. I really like what you did with the font/colors and the check mark over the i in staffing. Of your 4 logo designs I like your #6's the best, but I'm not 100% sold on it. Makes me think of a pinwheel or flower... Can you see entry #9? That kind of logo might fit nicely.
Interesting new deisngs with he briefcase and ties. But many of our jobs are lower level Drafters, Techs and Assemblers, etc that wouldn't lend itself to either. Perhaps some modern variation of the integral sign in a circle with the two-tone blue, maybe some shading for a possible 3D effect? Thanks.
