You aren't in the wrong place, you're just here late.
I suggest you read up and get better. Though there are plenty of amazing detailers here, those aren't the ones you'll find at your local shops necessarily.
I'd advise you to spend the money you would on a detial on a PC and some products and do it yourself. Heck, if you haven't damaged it much, there's no need for the PC in my opinion. My car is 12 yrs old as of last month and looks pretty good. I'd love to have a PC but I wouldn't say I need one.

Suggesting Products for hand use bought locally:
Get some microfiber cloths that can't scratch a CD (test them)
Get a wool or 100% cotton chinille mitt
Car wash, yadda yada, etc.
Cleaner/Sealant = Meguiars ColorX. Apply with foam pads, remove with MF cloths. Basically, follow instructions.
Clay = AutoZone has
Clay Magic which comes with lubricant.
Sealant = Meguiars NXT, available everwhere and comes with a little applicator. Also, just follow instructions.
If you are getting scratches, then somethings scratching it. I have thrown out a new wash mitt because it marred my paint. Getting proper washing down will minimize this. Since I don't know the condition of your paint, I'd suggest you use the cleaner/sealant before claying. I know, some people consider this overkill, but clay costs big money and there is no need to use more than you need. (Clay will remove surface and imbedded impurities in your paint. Cleaner will remove surface. Clay pre-cleaner = clay doing cleaner work. Clay post-cleaner = clay doing clay work.) After clay, rewash and NXT.
You will need to understand detailing, I'm afraid, Krelkor. Either that or you should have never bought the black car.
Take a picture and post it here if there is something about the paint that needs special attention.
I would never trust anyone else with my paint. There are daily horror stories here. Non-autopians come in and ask for help since some cheesy fly-by-night detailer had amateur night on the rotary. The horror...the horror...
