I have to agree with this.
I had to do both front wheel wells on my bus, almost as bad as yours.
Cutting it out is easy!
Creating new panels is easy!
Welding, my welds are ugly as hell but it is holding the two pieces of metal together just fine.
Here are my before and after pics.
Just remember to use ALOT of rust treatment, I used lots of OSPHO, and then seal it all up with some rusty metal rustoleum primer followed by some enamel or epoxy spray paint to seal it all up.
