Tiling over VCT tile wanting to use Mapei products

Hi everyone. Long story short I had to do an unscheduled renovation in my basement. There was a water issue that is now resolved. The previous owners had carpet on the floor which covered ugly VCT tile. I want to cover the tile in the bathroom and laundry room with porcelain tile. To all of the pros, my question is what Mapei products would you use for a skim coat. I am thinking of Granirapid. And can anyone recommend a tile contractor in the Metro Detroit area that uses Mapei products? Your time and help in answering my question is greatly appreciated.
