I have an 8x10 concrete slab right now, how much would it cost to pay
someone to extend it to an 12x12 slab? I would only have to add 2ft on
two sides and 4 feet on the other, 4th side is against hte house.

you don't mention the thickness of the slab, so no way to estimate the cost

it may be hard to find a concrete contractor who wants a job that small
(i.e. 64 sq ft, thickness unknown)

considering the small size of the addition, have you considered doing it
yourself?
