Eddie, by sheer coincidence, a friend of mine called round this afternoon to donate some wood for turning and asked the very same question. He has been asked to make some mirrors with evenly spaced scallops and a rebate at the back for a square mirror. I've suggested that he makes a female template by drawing the scallops using a compass or suitable round object and make the opening larger by the offset, determined by the cutter and template guide used.
In your case it would need to be a male template, Smaller by the above determined offset. What size are your signs, are they all the same size?, if so then one size template fits all!

The best advice that I can give a newcomer to routing is, learn to use the router mounted, this can be as simple as a board held in a vice, with the router firmly attached and a simple fence held with clamps, and when he/she feels competant and confident in it's use and is familiar with all aspects of safety, THEN, and only then proceed to learn how to use the router hand held. This is MY opinion, and may or may not coincide with that of the forum management, but is based on a lifetime of woodworking.
