to post many different ads for many different services, and trying to post in many different states, readers probably won't consider your ads (not you, your ads) "spam."
Under the scenarios you propose, I would imagine the site admins as well as the readers would consider it "spam."
I can't imagine your business model having an effective face-to-face element.
If you want to be a large corporation, be one. Take ads out in national advertising venues like all the big boys do. Problem solved. You no longer need worry that CL isn't a good fit currently.
