if you go down the self repair route, then i can lend you suction grip pliers to pull the screen off. Some of the more modern ipad screens are glued around the edges and you will likely need a heat gun to gently heat the glue. I've taken apart ipad minis and a few ipads, and every time the glue pattern causes issues.
It might be just as profitable to sell the broken ipad and buy a newer one rather than spending 100squid on a repair. Broken screen ipads can fetch decent money.
