I am putting together a website with a lot of theatre maps. At the moment, there is http://www.theatremonkey.com/LYTTELTONstalls.htm and http://www.theatremonkey.com/PRINCEOFWALESstMAP.htm which is hard to read and way too detailed. There will be some colour, but the illustrations will be SIMPLE with 6 shades and very simple. The style is to be like: http://www.seatguru.com/airlines/British_Airways/British_Airways_Boeing_777-200B_2.php with
I will pay per map; basically you duplicate the map provided from the link, I review and say what to shade, and then you can shade them in (5 minutes) and then it's finalized.
Please quote PER theatre map - some will be bigger than others but it won't be hard and just needs to look very nice.
