Need Some Suggestions Please

I have 44 domains all the same with 44 different American cites ie yoursitedallas,yoursiteatlanta,yoursitenewyork etc etc (these aren't the real domains) and can't seem to come up with anything quick, cheap and feasible to do with them. I have thought about classified sites, real estate, jobs, business directories etc but the market is flooded. PBN is no go as it takes too much time that I don't have They all have great DA,PA (average 30).
Any ideas would be greatly appreciated.
