Any car mechanics in the house?

If there's some solid material left on the exhaust pipe on either side of the break, a cheap yet solid repair can be made. You need some thin steel, not aluminum, sheet, not foil, about 0.05 mm should be right. A piece long enough to get a couple of centimeters onto the solid material and wide enough to wrap about twice around the pipe will do the trick. You also need two clamps, often called hose clamps. They're the ones with the screw that tightens the strap. Wrap the sheet around the pipe (you might want to pre-form it around a smaller pipe first) and clamp the two ends down. Then carefully wrap it with the Magic tape, paying special attention to where the sheet ends. The main danger is an exhaust leak into the passenger compartment, but if you do a tight job, you should be fine.
This is probably the best bet of all. They can cut the pipe back to where it is solid, and then replace the rusted part with standard stock. If there isn't any good pipe at the flange end, they can cut off the old, and weld new to the flange, or even replace he whole flange. I've no idea how much this would cost, since back in the days I did this kind of thing, is was barter between friends.

I concur with Pete. Back when I exclusively drove clunkers, and rebuilt cars, this is a situation easily resolved with a steel can, a wire brush, primer paint, and muffler tape. Also, check out the exhaust section at the auto parts store. There might be a small piece that can you can fit in nicely to replace only the broken section. The hardest part of working with exhaust systems is getting the old bolts off.
