You do not buff out orange peel, you sand it. It is fine and completely understandable that you would want to let someone else do the work, but there are plenty of benefits to doing it yourself. It is not overly difficult. You will almost always have more attention to detail when doing it, which can make a huge difference in the long run. There is only so much paint between you and bare metal, and a "professional" is going to go the quickest route in paint correction. That may mean they chew through more paint than you would on your own. Over time, that adds up and you quite literally can run out of paint to correct.
A real "professional" detailer will use the least aggressive method first. My practice is to tape off a panel and do test sections. Start with a mild polish/pad combo to see what it removes. I usually shoot forat least 80% defects removed, unless the customer wants more correction. Most don't care enough about the deeper stuff on their daily driver to pay for more polishing steps and removing more clearcoat.
Wetsanding will remove a considerable amount of clear. It's advantageous to have a PTG meter (one that reads ferrous/nonferrous metals and plastics) to know how much paint you are working with from the start. Then taking multiple readings per panel, as the thickness can vary greatly from panel to panel, and even from the center of the panel to the edge. And to make it even more confusing, if you don't pay thousands for a meter that will give you the thickness of each layer (primer/color/clear), you are only given an overall film thickness reading. You still have no idea how thick the actual clearcoat is. I would not advise a beginner attempt to wetsand.
That being said, a polishing procedure with something like a porter cable and a medium polish/pad combo (Light polishing foam pad and Menzerna Power Finish, for example) a couple times a year should be just fine over the useful life of a vehicle. I would not hit it with a heavy compound every year, but if someone has to do that, they have not learned one of the most important skills in detailing, that for some reason goes overlooked by so many:
LEARN PROPER WASH TECHNIQUE.
All those swirl marks come from touching the paint. Getting the proper washing tools, and learning how to use them to induce the least amount of marring, is the most important thing an owner can do keep their paint looking newer for longer. That, and keeping up with the sealing/waxing to prevent UV rays degrading the clearcoat.
Proper wash technique also saves a lot of time, since any future polishing should be very minimal.
