Need some bumper advice

[alorablue1]

I have a seat leon 2014 se model. Clipped the drive as reversing out. Damaged the undertray as well as the wing liner which has been replaced. However where the bumper meets the wing the 3 clips are intact but the metal bracket at the end broke off. Been told by few bumper garages that it's best to just get a new bumper. I have not taken it to seat just yet as I will think they will charge me too much. I have attached some pics. Any advice will be appreciated.
