Toll fee from Ayala alabang to makati

Is 164 pesos each way. So if you have a driver its going to be four times that per day. That's 656 pesos per day (roughly ten pounds)  so 50 per week or 200 per month.
This excludes petrol.
This is 200 pesos a day or 15 pounds a week.  So I am looking at 300 POUNDS per month
So as you can see it's costly. Of course I have not included the cost of my driver. As expats cannot really drive here.
