Bren, you could consider cutting off the top half of the root ball. Paint the cut (both pieces) with a paste made of a fungicide mixed with water . Plant the top and keep the bottom - it will produce new sprouts for you and you won't have to dig such a large hole. I'm not positive but your plant could be Anthurium schlectendalii. There are a lot of hybrids around though. Does it have red seeds?
