Thanks, CoG peeps 
My loosely formed plan was along the lines of @Woodman’s realtor friend - hit peak hours a couple nights a week, maybe Wednesday and Friday after work, or swing by the Pavilion when concerts when are letting out. I’m supposedly in one of the high growth areas, so I don’t think I’d need to waste a lot of time/gas running across town to get started. In town runs would likely mean dead heading back to the northern resource area. (haha)
I could probably get most of the city licensing requirements done in a day for under $50*, but wouldn’t plan to right away, if ever. (plus, I think you have to have made 20 runs, but really, big whoop there) An Airport permit is required to pickup at the airports, in addition to the city license, but I believe it is free.
I have no delusions of it as a get-rich-quick thing, closer to the beer money scenario - throw some extra bucks at some bills; save up some fun money for recreational outings like going to a race or fishing/hunting; etc. (I’ve never been hunting, but the guys I’ve been fishing with invited me to go with on a hunting trip this fall, which is not in the budget right now.)
*supposedly under $50, but I’m dubious… Fingerprinting - $11, City fee - $11, Fire extinguisher - $10-25, time & gas; physical & drug test $?, warrant check $?
