Agreed with doing detailing yourself.
However, I think one comment you made might have been overlooked: "...bunch of scratches ranging from light to heavy." It's the last word, heavy, that has me a little concerned. If your fingernail catches on the scratch, it's possible you won't be able to correct it all the way as new paint work otherwise could. If you're OK with that, and not having "(near) perfect paint, press on with the recommendations above, get the kit, buy Mystery Boxes, etc. If not, new paint may very well be your best option to begin your Adam's adventure!
Recommend you post some pics of the worst damage and let the experts on here weigh in.
