It's cheating. Cheating? Well, it would be if there were rules about what you could write to get to 200 words. But, I don't think there are actual rules and there aren't any software alerts saying, "Hey @motherf&*$%er these words Don't COUNT!"
Ad Network - think Google or BuySellAds
Affiliate Marketing Manager - seems like a job - unless you're managing the marketing to your affiliate page - then you're in business.
Apartment Locator - cities support these kinds of services helping new-to-towners put down some roots once their AirBnB tolerance wears thin.
Concierge Service - provide some service for people.
I think of productized services when I read that one above, but the intent of this one is to provide a high-touch service for travelers. They buy online, tell you where they're going, and then when they get into town, you pick them up with a limo or van and concierge the heck out of them.
Email Reminder Service - this one sounds like something a programmer would think, oh, I can write a script, I'll automate some email reminders. The next thing you know, they're running a $1,500,000 business from their laptop and a couple of AWS servers. I like that one.
Private Investigator - My mom was always so nosey, she thought if she wasn't an elementary school teacher, she'd have been good at this. People would never wonder what the gold Buick was doing parked outside their favorite hookup spot.
Two hundred words don't give you much room to elucidate. Stay tuned for more.
