Professional & Contemporary "Nautilus" Logo

Seeking an innovative, clean, contemporary and professional logo for Nautilus Legal and Nautilus Title, a legal services firm and a title company, respectively. Would like to see two versions of the same logo, one showing each name. To be used on business cards, signs and letterhead, thus the winning designer may be hired for additional designs incorporating the logo into such items.

"Nautilus Legal" & "Nautilus Title"

Would like a logo design based on a Nautilus shell, using one or more interesting colors.  Prefer to see something in dark purple, royal blue or a rich red, with yellow or orange as an accent color if necessary, although prefer use of only one color other than black if possible (for printing cost reasons).  Will consider other colors if the design is eye catching enough.  Want to use the logo for both Nautilus Legal and Nautilus Title, so will need to see it with each name separately.  Prefer a professional, clean and contemporary design to anything artsy or cutesy, somewhat abstract or modern looking would work too.  Plan to use the logo on business cards, letterhead and signs for both the law firm and title company.
