Saudi and pakistani market is different also the environment plus car paints condition. People say here in pakistan that we don't need to get done these detailing thing as car is new. People are more into self made packages. It is not easy to redirect to them in right direction. Your base price is aimed much high. This cannot be easy to convince the customer for wax only in 30k.
Here you will meet some customer who will just say and degrade you and your service by saying "you only get this bottle for 6000 rs and applying on 8 cars and charging us 20,000. People don't see the tiny little portion in human body which takes edible input to survive for a life as its under the skin no one can seen it unless cut it 
People don't count the other material cost, wear and tear of tools, other liquids place maintenance and plus labor cost.
Anyway my piece of advice is start it and don't put and stick to your packages. You have to modify things according to customer needs. Customer is best teacher once you put your feet in market customer will teach you that what he wants. You have to manage the things on runtime bases as well.
