I have a friend here who owns a company doing graphics for the police, and all other things. I looked up the definition of Intrepid myself, and asked a estimate. He said around $25.00 with Intrepid in 4in letters, and the definition in 2in letters.
This guy recently did the word "Deliverance" on my windsheild, and I am debating on doing the definition on the back as well. The letters looked great, came out just like the logo of my website Deliverance.
