Trades & Labor Garage floor tiler

I want to tile my concrete garage floor. This is a forlorn hope, but does anyone know a good tiler.

 

I don't know the name of the person who laid the floor tiles in our house but if i did i would tell you so you don't use him.
Not long after they were laid cracks started to appear just by the weight of us walking on them.
After going around tapping them with the plastic handle of a screwdriver many of them gave off a hollow sound meaning not enough cement underneath them.
If you intend to put a car in your garage i would forget about tiling it.
Oh i just also remembered, don't get whoever did City mall tiling.
