Exhaust manifold on '95 Corolla - easy repair?

I've done a fair amount of basic maintenance on my cars, but I'm told
the replacement of the exhaust manifold on my 1995 Corolla involves some
difficult maneuvering underneath the car to get at some bolts that can
be pretty hard to get off as well. I don't have any way to elevate the
front of the car, so I'm wondering if this is a repair I should attempt.

Can it be done without ramps or a lift? If not, how much time should I
expect my mechanic to spend (replacing manifold and heat shield)?

Also, if I get the parts myself, what will I need (gaskets, some kind of
installation package, etc.)? I don't have access to a shop manual.

Thanks for any info...
