Vibration (like bumping) while car is in motion

When I accelerate the car vibrate (just like as if it is bumping) and at higher speed the bumping goes more frequent but small in terms of vibration. I showed this to mechanic and he advised me that I need to change a lot of things. Some of them are ; inner tire rolls, front truss, tires and alignment correction. I couldn't understand much but is the first one inner tie rods? How much cost should I expect in repairing?
