I made my own. Had Jeff at Loud Graphics www.loudgrahics.ws do the vinyl and then went to metal place and picked up stainless steel. Total cost for a 4x3 foot sign was 45 bucks (16 for stainless steel and 29 for vinyl). I had several quotes for 150.00 and 200.00 but found it so easy to do. You could probably do 5 signs for what it would cost for 1. This is very easy to do also and it only takes roughly 10-15 min max.
I think as far as signs go its better to get a local maker to do it. You can talk with him face to face and in detail explain exactly how you want them done. I get all mine done from a local maker, because i can draw out the design i want and he will copy it exact.
