Am I getting overcharged ?

Had an accident on E311. Damaged my front hood, bumper, right headlight and the metal structure that hold the radiator/ lights in place. As per the garage this is going to cost me 7000 AED.

2500 for the hood (new ) 1500 bumper (new) 900 for the light (new) 1000 AED for the metal to be repaired 1000 AED Labour

Am I getting overcharged ? If yes, how much less can I get this done for and from where?
