Clumsylass, ifixit does not do repairs. Here you get some parts and all the free advice you need to fix it yourself. Here is the guide you need, as for the availability of the part, I'd check with Google and see if you find something close to you. Hope this helps, good luck.
It seems you have to replace the whole display assembly, which is about $200. Hope you could afford it. After googled, you can find the new part from Amazon or other online store. But please make sure the new screen is original before purchasing.
All of the shops in my city charge US$175-$180 for the screen replacement. The instructions are here, as are the parts. You can also find the parts on eBay, AliExpress, and other online shopping sites.
Samsung phones are fairly expensive to repair. You can buy a screen off eBay or amazon for a lot cheaper than a repair shop would charge you and if you have someone who is good at DIY you could ask them to do it for you. There's plenty of videos on YouTube explaining how to do it. I would also suggest investing in a good sturdy case :)
