Wow... its rather great that the publisher is fairly open to things like this and posted directly here. Anstett, did you happen to invite him here to chime in or was he made aware in another way?
In any event, I am glad you were able to get to a point of knowing exactly what was an was not acceptable(and without being sued to get there!!!!). I hope you find some one to take on the work. If it were someone more my style, I would offer up, but...well cities are not my thing(not that there is much I could claim "is my thing"...lol)
