wow, there are numerous mapping systems you can use, from the most detailed GIS Arc view etc... to some generalized you can create yourself. I used to do the mapping for a telephone companies fiber plant, I had to create the maps using notes from lunch napkins so I know what a mess it can be. Send me a private message and I will try to help point in the right direction.
