Can someone recommend a repair place in San Diego?

So the front corner often trailer is pulling away from the side a good bit. It wasn't too bad at one point, so I attempted to fix it myself. I got it all buttoned up, then after a trip the the river, the gap was even bigger. It's going to need some pretty extensive work done to it. None of the mobile guys I have called will do it. I wanted someone to come out and fix it, that way I can watch it done, and we could build it back stronger than before. One of the mobile guys that came out said he thinks the frame flexing is what caused this to happen. I know WW is notorious for their frames, but mine was built after the supposed fix was figured out. I don't want my trailer to go to a place the has 200 trailers in the yard that need to be repaired, and they are just going to fly through them. I want a company that will take the time and detail needed. On guy recommended San Diego RV center, but like all the places I've looked up, they seem to have mixed reviews. Anybody have any recommendations? Any help is appreciated!
