Repairs of electrical switch, contact and socket

1) Electrical socket is working, but not attached properly. Should be fixed into the wall. 2) Light switch to the bathroom is not working properly. The light switch is on the same panel as the thermostat. Should be either changed or repaired. 3) 1 of 3 lights above the bathroom sink does not always switch on, the left one on the picture. There is possibly bad connection that should be fixed. Please suggest a price for all 3 tasks, not per hour.
