I heard CityCab do have a scheme for freelancer cabby .
What they do is : U go and sign up a Crown , minimum 3 days ,
pay full amount $88 x3 , and u can OMO for just 3 days .
Any day .... there is no specific time u must sign out ... but
there is a time u must sign-in back to them .
Like hotel style , check-in , u can do it anytime , but to
check-out , must be 10am .
Same Rules & Regulation , same Security Deposit .
Also depends on they have taxis availabilty .
