Clean logo needed for law firm

My clients like the attached logo in the zip file but they want variations or similar ideas.? It needs to be a clean, relatively simple logo - not graphics heavy.? It should be able to reduce well to fit on a business card and still be able to read it. The website colors will be blues and greys so the logo colors should be able to interface nicely. I am requesting the winning bidder to submit 4 - 6 logo mockups / concepts.? Finished logo file should be high res jpeg (plus psd/tiff file if used). Please contact me if you have any questions.? Thank you for your time, Patrick
