Hi Shawn,

The scale of this project is colossal! City maps (even small ones), much more so than continental or world maps, are very time consuming to draw - so if you want a city as large and incredibly detailed as you've described, I think you might struggle to find someone who is prepared to take this on for free and last the course (I hope I'm wrong).

It might sound daunting, but you could try and have a bash at this yourself by checking out the numerous tutorials here and having a go. I think that having an oblique view rather than a plan view might be a bit too much to begin with, but a plan view would be a good place to start in any case.

Best of luck with your request!
