i believe you live in lahore which i considered cheaper from islamabad.
i got some of work done in the following rate.
clutch and pressure plate 4500 rupees (Excedy japanese) and bearing 1100 and small bearing for 200.
gear oil ZIC 75W85 1500.
rest i dont know.
by the way who ever is charging you 15000 for paint job should be punched right on the face.
take car to suzuki 3S body works and they will charge you the same of paint job and it will be exact colour match with the rest of your car. (until or unless you are already getting it done from 3s)
i would recommend to take quote from somewhere else.
