If it just the floor edges that are rotten then a competent welder should be able to make up angled repair sections .. They use "off the shelf" angle repair section. If the Pans are rotten he will weld in whole floor repairs i.e. the bottom of the pan each side .. Depends how far and bad the rot is. I doubt if repair panels are available .. no need..
Save money by removing the carpets and insulation before taking it to welder .. Make his job as easy as poss.. Welders hate stripping out interiors and it bumps up the hours quite a lot.... Drive there with just the drivers seat in .. Afterwards give it a good dose of rust killer on the inside..
In the old Triumph, MG ragtop days, which also rotted from the inside out. I used to paint the inside pans with waxoyl underseal and then when still tacky stick a polythene membrane onto the underseal.. Keeps the inevitable damp/wet carpet/sound insulation off the metal..
Downside of a spider in this climate I'm afraid..
Gettin' to old for this sh*t
