These signs are made of sturdy, durable corrugated plastic and can be printed on one side or both.  
Design charges are not included in the price.
H Stakes are made for use with corrugated plastic signs.  These stakes are 30" tall and will keep your sign roughly 14" off the ground.  Sometimes labeled as a "step stake", the bottom rung is more for support that a step but will assist in getting the stake into the ground if needed.
H Stakes are $2.00 per piece.
