Tiles - cleaning?

Question:is there a tradesman that could come out and clean an area of 2.5mx0.5m of mosaic tiles to their original state they are covered in hardened wall tile adhesive which due to arthiritus i cannot remove due to the amount of scrubbing needed. i have used brick acid which has taken some of it off.

i would appreciate if someone could quote me on this unsual job - the house in Brogborough Bedford, MK43, UK - i require someone urgently - thanks
