Our MTLine don't do guard duties. We do our own duties, namely
duty ambulance, duty driver x2 and duty specialist.
Duty driver and ambulance i am not sure but duty spec weekdays the
market price is around $40 (because stay out unit) and weekends
around $60 - $80.
I didn't sell weekday duty spec because i really don't see what's
so hard about doing it but for weekend duties and public holiday
duties i have been selling it ever since i got posted in all the
way til i ORD (barring extras), sometimes up to $100.
