Welding, small job help

[Doc45]

I have a 2003 Tahoe with factory step rails. The mounting bracket for one of the mounts broke at the rail, I'd like to get it repaired as opposed to just removing the rails (even though I don't use them they look nice on it). I'm in Centennial near Arapahoe Rd and I-25. Anyone have a recommendation for someone that would handle a small job like this? I've tried a couple of muffler shops near me and they didn't want to/couldn't do it.

I can weld it up what does the back side of the break look like.

Sending pm with a pic of the underside break, thanks!
