Hey Jake! We recently built a website like you’re describing for a multi-store operator through Laundromat Resource Marketing. I’ll drop a link to it down below (we only designed the site for this one, not the graphics and logo). We’d be glad to help you out if you’re interested.
I’ve also heard good things about Spynr marketing company with laundromats so they would be worth checking out, as well. Congrats on the portfolio!
