Mazda - Protege :: 1996 - Front Turn Signals Malfunctioning / Wires Cannot Be Reconnected

1996 Mazda Protégé, 128,821 miles, in town driving 5000 miles per year in recent years.

I hit the frame of my garage door about 6 months or more ago which partially pulled off the front bumper area and knocked the right turn signal lens and headlight out of whack. My handyman fixed it up, by using good quality baling wire so the turn signal and headlight etc worked.

Then, I did the same thing a couple of weeks ago. (I was trying to avoid hitting my bicycle which I had just had reconditioned for an ungodly amount of money) My handyman is unavailable to fix it again. I have gotten stopped once by the police for the malfunctioning turn signal so it was time to get it fixed.

Mechanic (same one as previous posts) said it will cost 1500 to replace the bumper area etc so the front turn signals will work. He absolutely insisted that the turn signal wires cannot be reconnected. He reattached the bumper area "temporarily". I am willing to pay to get the turn signals functioning but do I need to replace the whole bumper assembly unit?

Does this seem plausible?? I just want the turn signals to work. I do not care about how it looks. (I drove the car in the interim with a bright yellow bungie cord holding the unit together)
