Screen shattered blackout and bleeding inside

I want to repair it on my own.(I can manage to hit certain buttons sometimes and accidentally make a call.)

What are all the parts and tools will need to buy and will I be able to find an easy step by step way to take it apart ,fix, and then reassemble . I'm betting this is cheaper than a company doing it or getting a new phone.

Thanks. Adam

Any other info you could give me before starting this endeavor

I have a Galaxy a,14 5g i love the phone, I called around and everyone wanted. Around $110 to fix it. I'm on fixed income so there are some things I just can't buy. The guy told me I could bring in my own screen and whatnot I really don't know what all parts I have to buy.

Just for reference, I can make call sometimes. It landed on its right side. And smacked screen first I could work with it for a while but now I can't touch any of the messages. It's hard enough to just unlock. The whole right side (while looking at it) has ian inky look and it has several red lines and some green. That go from top to bottom. Again it is starting to get really inky and harder and harder to do anything with.

I wanted to add pics maybe that would have been useful but I get get them over here to the question box here
