Kick panel rust

[Lippyp]

On examination I seem to have the usual rust hole at the bottom of the passenger side kick panel just above where the floor and kick meets the drivers side doesn appear to be holed but I need to give it a good looking over.. Obviously I want to repair this properly. Does this mean removing the wing (fender) and door and how involved s this? does it mean removing the grille etc first, in other words exactly how much will I have to strip down to get reasonable access to the area as the work will be done outside. Also any pictures of repairs in progress in this area would be appreciated as guidance. Hod difficult an area is this to repair properly, it's not a huge hole and the floor appears sound although I've not given it a really good prod yet.

All advice gratefully received.
