That side shelf looks like it's creased and beyond repair, but depending on who does the work, maybe you could cut it off, then fabricate and attach a similar replacement. BTW looks like the front of your CC is already drilled to install a shelf. You might be able to find or make something to go there. Imagine for example one of those long narrow cutting boards for French bread. Or any shape of cutting board, as long as it can span those two holes. Some toying with a drill and some nuts and bolts could easily put something together, and you could still dismantle it if you want to bring it in for washing.
Maybe you can grapple and bend the cooking chamber pieces back into line. The hinges might be damaged. Not being able to open it now is not a good sign. Is the firebox OK? Looks like the lower shelf is good, probably the legs too. Does it stand level, or wobble?
