20m2 then knock a bit off for discount and quantity so 2300 less say 300 gives 2 g in your hip or 25 m2 so 2875 then knock it down to 2300 to get your 20 quid a m2
again mate depends where you are in edinburgh where i am id charge 25 then knock down to 20 for that size, might even take to 2200, some places would be around 15 a metre, you have to work out what you can do a day i reckon 20m2 a day then grouting so 7 days at a day rate of 150 is 1050, again depends how fast you are then it might be anything from 15 to 30m2 a day so good cash
if they are supplying mats make sure its good gear and not b&q or wickes own make

standard 10% for waste etc thats 1400 tiles lol
