Really can't make out any damage from the pics other than the broken fog lamp and slight gap at the top. Believe me my rear bumper looks worse. My only worry is your observation that it is difficult to close the boot door. Otherwise this definitely is a minor job of removing the bumper and refitting it. I did that at TASS once and they charged me Rs.350/- The fog lamp would cost around Rs.760/- plus shipping. If you are planning to do the work outside, you can get it from 99rpm or try to source locally which will save you the shipping costs.
