Here are a few of the questions you will want to answer before requesting a custom sign sample image and price quote:
What size will the sign be? Will it be for indoor or outdoor use? What colors do you want the sign to be? Will you want text only, logo only, or both on the sign? What font do you want to use for your sign? How large do you want the letters to be? How far away is your target audience? What type is your target audience, passing cars or pedestrians or both? Do you want a part of the sign to flash or all of it to flash?
