need a logo design

I'm looking to have a logo designed to suggest a simplistic arched bridge in blue colour. "SCI" letters will be the bridge, right at the end of letter "I" there will be a painting spray gun to suggest the letter has been sprayed on. Also, the pattern of the written letters to suggest they have been sprayed on. Under the Bridge, will be a full company name "SPECIALIST COATINGS & INSPECTION"
Right above the bridge, in the middle, smaller, will be a papyrus with our philosophy written on with Latin characters: "Carpe Picturam"
