You came to the right place, unicorn lover; that's what this site is all about.
I have bad news and good news. The bad news is that iFixit doesn't have a guide for your phone, but the good news is there's a Spanish site called Nadie Me Llama Gallina (Nobody Calls Me Chicken) that has exactly what you need.

The automatic translation on this site seems to work fairly well, with a couple of little quirks. The translation for "battery" comes out as "drums" and "flex cables" come out as "tablecloths" but otherwise you won't have any trouble following it if you're not a Spanish speaker.
You'll need to get together some tools; you'll need a thin metal opening tool, a set of plastic opening picks wouldn't hurt, a #00 Phillips screwdriver, a plastic spudger and a source of heat; the iOpener is a good choice, but a hair dryer will work fine if need be. You'll need something to take out the SIM tray; a paper clip will work in a pinch.
For parts to start with you'll need a replacement screen; those can be gotten in several places like Amazon, eBay and AliExpress among others. Here's one of the first ones to come up on a cursory search; you can undoubtedly find more options with a more extensive search.

Finally, you'll want to try and locate some precut adhesive sheets in order to put the phone back together again when you're done. There are three kinds you should get.
* Screen adhesive
* Rear cover adhesive
* Battery adhesive
That should get you going; feel free to come on back and ask if you have any questions or need any help along the way. Good luck with your repair; let us know how it goes!
