Somethings broke

Drove car to work and I thought it was better as noise/vibration was getting better but after motorway journey the steering became very very tough, like it lost all power steering and its a little easier when moving faster than 5/10mph but its almost impossible to turn at low speed or when parking

The power steering fluid was black/oily when I checked it the first time.
I can also feel a lot of vibration through the steering wheel and almost like I can feel some sort of belt or pully as I can hear it when sitting inside the drivers seat. Almost like a whirring/windy noise or a sort of (shhhhh)
Ideas?
How much roughly?
I will take to a garage today but is it likely they can fix it as I have a 30mile drive or is it a breakdown recovery job?
