Check Tractor Supply. I think they have a "professional" grade with your requirements.
CLOSE! I can see the quick offset. The tilt that they refer to is to tilt the blade (in plane) forward or back, giving the scoop of the blade more or less bite for digging. The tilt that I am refering to is different. It's to tilt the blade down on one side (while the other side goes up), for digging drainage ditches and things like that.
