Seconding Micro Center. Also seconding the idea that replacing a laptop LCD isn't usually difficult, but I have never dealt with OLEDs (which are thinner and likely more fragile than LCD panels) or touch panels. See if Asus has a repair manual and/or video about it.
You could probably send it to Asus, too, although they don't have a great reputation for service (they are an irritating company, actually--they make excellent products, but have lousy support; the good thing is that the products are good enough that the support is rarely needed).
