Most Panel beaters will charge €200/300 at the cheapest.
Depending on number of panels affected, paint type ect.
If they are only small you could look at getting a scratch repair kit from halfords or a local motor factors.
I have does this before on a few scratches, but they were kinda hidden away.
If you take your time you should be ok.
Though if it's a new car you may want a professional job done.
