is the cement on the back of the tile or the front? what kind of cement is it. is it adhesive? is it a glazed tile? if the cement is on the back of the tile (which would be what i would guess ) then all you have to do is lay the tile on a table ( out side ) and nail some wood down in a "L" shape and put the tile on the inside, and get an angle grinder with a masonary wheel and grind away. please wear safety glasses, you will really need them and you're off to the races. i have done tonns of theese and it's really not as hard as you think. watch your fingers, and good luck
