So sorry to hear about the accident! Fortunately, an aftermarket 2001 Ford Ranger front bumper can be had for as cheaply as $150, but that’s without mounting brackets or installation. You may spend a bit more, depending upon the parts you need.
Now, if you have a bit of automotive expertise and the right tools, you (and your nephew?) may be able to replace the bumper yourselves, which would eliminate the labor costs of a professional mechanic. Because the Ranger is such a popular truck, you should be able to find instructional videos, walking you through the repair.
