Want to refine our logo.  I want to keep the shield unchanged, except for colour or more realism.  The font of the text and orientation need work.  I really like the Suncoast Diesel logo.  

Hi
I like the layout of #13
I like the font of Suncoast diesel.  #9 got it closest. 
All white, no orange though.
Supertech shield must remain in tact.  Shading / filtering adjustments ok.  This is an established logo, on all of our branding.  I cannot change too much.  Thanks.
