Never too late to learn. How you came off seemed rude and demanding. Most of the time with a project like you are trying to accomplish, the files are not just going to be there and ready. You will have to put in work with it. Everyone starts somewhere with editing. I recommend looking on YouTube for tutorials depends on your editor. I personally use Adobe Premiere for most of my work. Adobe has a 30 day free trial of it.
I actually tried to do color correction with one of my own projects, but it seemed too hard and too complicated. Also, I am personally boycotting Adobe products because of the lack of a perpetual license, so if you know of an alternative, could you please let me know? Thank you.
