Get this washed and waxed from a good place before taking to denter.
Either denter or polish wala can get most bumper scratch removed with rubbing polish. Shouldn't charge more than 500.
Bonut and door needs some touchup paint work and may be denting. It should be a one day job (few hours). May be 4000 but depends on the condition and denter. If you want a proper repaint of door and bonut then it will take a few days and more money, around 10000.
Repaint dont look necessary but it looks nice and clean after repaint. You might not like the touchup
