In any broadcast medium the broadcaster is expected to conform to community standards so somebody will have to watch the ads and do some editorial selection.

As for production values, look at the ads run by local car dealers, furniture stores and such. Images with text and voi eovers play well. If all else fails use the "Ken burns effect"

A person with a month or so of training and maybe $5k of gear could produce a few ads for a customer in a day and you have to hook up that person to the customer.

Yes, I understand that it probably wont be possible to run instantly. But manual approval should be possible within 24 hours, allowing for next-day ADs.

As for local Ads, in my country India those are run only in "local cable channels" which is basically some extra channels inserted by local cable providers (in US, I think(?) there are only nationwide cable providers). There is little scope for such deals in mainstream channels.

We have local channels put together by the cable company (and the phone company in some places), too. They mainly have video of community events, like town council meetings or school sporting events. There are a few that have tickers and scrolling panels with various topics and combinations of topics (general news, financial news, community news, weather, sports scores, stock ticker, etc.).
