Pricing for tile installation along with floor leveling

[Kalpesh Patel]

Hello,

I need to install porcelain tiles in my house, however, the floor is not leveled. How much does it usually cost to install tile as well as level the floor? I have a guy who said he would install a tile and level the floor simultaneously, like marble installation, one tile at a time. He said $5 /sqft. Is that a regular price? 

Please assist if you know the answer. Thanks a lot.
