Real Window tint is paper thin. You can crease it just by moving it. I can wrap a car blindfolded... But it took me three tries to tint the windows and it's "acceptable for my use".
Tinting isnt hard. The learning curve is small... If you can install vinyl, you can learn to do tinting. .. making it look perfect isn't easy on your first job though . It's doable... you'll likely be redoing a few windows as you go, But unless you want to get into window tinting more often... I wouldn't bother. Not worth the headache for a one off!
And whatever you do... Don't buy the Amazon / hardware store crap. I see so many vehicles and store fronts with bubbly windows... Everytime I do I look back at the tint I installed to keep the sun out of my kids eyes... Not a single bubble or show of age and it's been years.
