I've generated some interest in my area with creating a website where local business would pay a small fee to have their ads posted. Because the fee per ad is low the only way this model has long term potential is if it is 90%+ automated. There are several plugins out there, but I'm interested in hearing personal experience from anyone who has used one. I don't want to sound like I'm promoting any given plugin so I won't comment on my top choice so far. Ideally, I'd like something that allows advertisers to manage their own accounts and payments. Anyone have personal experience with one of these plugins?
