To me, it looks like your vehicle might be too damaged to fix in just 3 days.
The damage looks as though it may have bent the radiator brace in the front. In many cars these can easily be replaced but time would need to be allowed to order the part (if it's possible to order the part)
As for the front bumper, it looks like plastic which can not be 'beaten' out by a panel beater.
The bonnet may be able to be straightened out as well.
I can come for a look but I'm in Geelong so it will require adequate notice. I can help you try and source the parts from an auto wrecker and install them for you.
Cheers, Matt.
