The pics look great of the DIY jobs. I too am a DIY'er and rarely pay someone to do any work for me. Wife was yelling at me to hire someone to add sun shades to our windows. My arse is out back making frames and adding sun shades for a fraction of the cost lol.
I too was going to do my own liner but honestly Line-X was on sale at a local shop for the premium and they did my truck the same day I called. Dropped it off, picked it up a few hours later with a warranty and a beautifully protected bed. I would just pay to have it done.
