We build & manufacture any size sign and install it.  All signs can be UL approved or not.  Prices will vary due to size.
Oversized signs such as  an 8'x 8' electric sign, I would recommend Flex faces versus Plastic faces.  All electric signs come with a 1 year warranty on the ballast only.  The cabinets are made of aluminum framing with raceway for fluorescent HO bulbs.  Signs can be one sided or double sided to meet your needs.
