Touch-up paintwork

[Sosaria]

I've never actually bothered much with the tiny scratches received on my car over the years. But recently, while reversing into a very tight space, made tighter by an illegally-parked car , part of the right side of my car was scratched by carpark pillar.

 

Now there's a few streaks of purple paint in a circular area roughly 15 cm in diameter. No dents. I think it's a good time to fix up this problem, and all the other little scratches here and there, by repainting the affected areas. Never done this before, so would appreciate any recommendation of a good place to do this: location prefer Jurong/Pioneer, open on Saturday or Sunday mornings, price estimate (don't want to get )?

 

Or anybody here has alternative idea how to fix the above problem without repainting and save my $?
