I'm interested, though I offer lots of different styles of maps from mostly hand-drawn to completely digital. Check out my Challenge winning maps - see the "buttons" or compass roses under my name - click on any of them, though some are encounter scale maps, instead of regionals. I think my hand-drawn style would compliment that city map you have there.
While I am currently working on other map commissions, as well as my own published setting, I still have time to take on other commissions.
Here's a link to my portfolio, though any map made last year isn't in that portfolio yet...
Let me know what you think, I am interested (I will send you an Email...)
PS: I run a digital print shop, so I can certainly make maps for any print resolution you need.
