I replaced my screen and digitizer after I jumped into the lake with my phone in my pocket. Everything you need can be found on amazon. I'm on mobile so I can't find you links just yet but I've made a previous comment about everything that I bought. Let me see if I can find it and I'll link you to it.
Edit. Found it faster than I expected. Here ya go.
Buy a new digitizer off of Amazon. I'll try and find some links of the one I bought. I did the same thing to mine and taking the phone apart isn't really that hard if you have the proper tools. There are good walk-throughs on YouTube that you can watch to ensure that you are doing it properly. Buying a digitizer, adhesive, and the tools will cost anywhere from $70-80.
Edit: here are all the links that you need to replace your screen. I would buy 5mm, 3mm and 1mm adhesive. The 1mm is used on the sides. There is also a second part to the video that goes into detail about reassembling the phone. If you have any questions feel free to ask.
