Let me give you an ideal what a fair shop would charge:
I just had an 02 Impreza with a 2.5 SOHC in the shop. For just shy of $1200: T-Belt Kit, seals, thermostat, rear wheel cylinders, NGK IX plugs (#6), valve cover seals, brake system flush and filled it with coolant. Used Subaru parts for the seals and t-stat, Gates for the kit. The price included parts and labor.
