How much would a tiler charge to lay 12 sq ft of porcelain tiles 600 x 600?
600X 600 would be approximately 27" X 27" tiles and that means each tile is over 4 sq feet if that is so, it is highly unlikely that you really only have 12 sq feet to do, what I suspect you mean is a room 12 feet square which would be 12X12 or 144 square feet, OR you may have a counter top or entry to do & it may in fact be 12 sq feet... Install pricing varies widely from city to city and even from one tradesman to another, I have seen $6 per foot with one guy that is always busy and an hour later another guy offers to work for $2.5 per foot. The quality of the work is another variable, not every Tile setter can do every job. Small jobs are usually priced as a Minimum & that can be anywhere from $200 to $600 flat fee. Minimum labor charges not withstanding, I would use $6 per foot as a minimum if you have over 100 sq feet or $600 minimum if the job is small. Dont forget they will not provide the thinset, trims, backer board or the grout that is all on you too. Hope that helps

Define Busy waiting?
"Busy waiting" is the act of actively waiting for some condition to change. In programming microcontrollers, one might want to wait for a pin to become high or low before continuing with the program. A "busy waiting loop" in C would look like this: ... while(PIN1 != HIGH) ; ... This essentially does nothing but check the value of "PIN1" time after time, waiting for it to become "HIGH". Now, if PIN1 were to become "HIGH", the processor "breaks out" of this busy-waiting loop and continues with the program.
