My BMW front bumper was around 1300 to replace and paint it, through BMW. I went through insurance, same $500 deductible (allstate). They charge an accident surcharge when you have an accident at fault, I don't know about for non-collision. I can't tell how deep the damage is, but without paying a buttload in labor I doubt it will look right without either replacing the doors or a ton of labor. I'd rather go for quality work, either way.
At this point you don't know if it will affect the windows going down, I'm assuming.
The bumper may not be too bad, and if it's on the surface may buff out. Is yours a 28 or 35? I can't tell.
