Mural Paintings for Gym

I am looking for an artist willing to paint some murals of Philadelphia on some blank walls that I have in my 18,000 sq ft fitness center (Retro Fitness). I'm not set on what, but looking for Philly themed ideas (art museum, skyline, portraits of historical figures, etc). I have 3 walls that range around 20 ft wide by 10 - 15 ft tall. I'm open to ideas and suggestions.

I would like to see past examples of artwork completed.

Also willing to trade services for this with a free gym membership. I also have a medical spa and would trade Botox, fillers, facials, microneedling, vitamin IV drips, semaglutide, HRT, peptides, etc if you are interested.
