For those of you asking about printing, i can usually take your file and make it look pretty good.  I can size it and print it exactly as you specify.  the colors and quality will be top notch, i am printing these on a 150K photo printer.  However, they do not look good backlit, they are not trans light material.  If you want a backlit marquee, get them done elsewhere.  Otherwise, i think my stuff works out really well and i am selling it very reasonable, everyone has been happy so far!!
