If you haven't already take issue with the lab over the non push on your HP5. An any time you have a special process write it on the roll or cannister with a sharpie pen so the lab tech will see somethings up and possibly double check even if the instructions weren't passed down the chain of command properly.
If a lab wants your business that means earning your trust, which means doing what they are told to do!
As far as the wedding business if you can trust your lab you can make more money by shooting more instead of doing the footwork in the darkroom. Save your darkroom skills for special projects.
