If it's only two torx screws holding it in I wouldn't dream of paying someone to fit it. Seems a bit expensive if the parts £91 when only a year ago it was £61?
My Leon FR had spline screws not torx - star shaped with more like 20 points - torx are only 6 pointed star screws... Bought part direct from seat for £59 and asked garage guy to borrow his spline tool as spline bits are hard to find...
