You're right that not only drying causes swirls, but using a two bucket method with a quality wash mitt likely won't cause any swirls.
The way you described washing your car is the exact reason cars get swirls on them. I'm sure your car looks good from a slight distance, but upon closer inspection I would be willing to bet money the paint has it's share of defects.
I stick with my suggestion for the OP... Find one of those places with the pressure washer/hoses, bring your own gear, and hand wash it yourself. Just try not to go during a super busy time, or they might get on you for hand washing.
Or you can spend a little extra coin and go with the waterless wash system from Chemical Guys.
At the end of the day, it's your ride so do what you feel comfortable with.
