Some forums don't like it when you link another forum but on this occasion i will and if the moderators don't like it, i wont repeat it.
Everything you need to know is in this thread. click here.
The first time i went through the process (first map i did) it took me about an hour. After that it took me about 5 minutes per map. The delay was that when you are putting in the information regarding the maps, it was all case sensitive. Bloody frustrating! otherwise the instructions in that other thread are great.
The main thing with copying the maps is to get them to an 8 bit tiff file, but i just get the copy places to scan it however they can - usually 24 bit and then reduce it.
Originally i had my maps copied at the Triangle Copy centre on Burwood Road. i've had later maps copied at office works but i think they put them through a roller type copier and a small crease in the map made it slightly off kilt.
If you are going to give it a go, i'd be happy to help out if required.
