brake lights stopped working all of a sudden

My brake lights stopped working all of a sudden. My fuses are good, and all the bulbs are good. Every brake light stopped working, my L and R, also the one in my rear window, and the one on the trunk. Someone said to check the wires on the hood hinge, they all look intact and un-disturbed. I was also told it may be the brake sensor under the brake pedal.

If that's the case, how much am I looking at spending.

Thank you for all the help you provide!!!!!
