I detail my own boat. It's a 1996 Bayliner Trophy 2002 I picked up recently for 3k. The boat was in horrible condition. I power washed, compounded, and polished the hull. same with the cabin exterior. You can easily do it by hand with a lot of elbow grease. I picked up all my supplies from Walmart and Amazon. I used simple green for the seats and then used spray foam cleaner for the cushions and headliner. Always be carefull not to apply to much force on the headliner.
