Replacing stove pipe on a wood stove, is this something that can be done by my husband, or do we need to hire it out?

We had a need to replace a section of our wood stove stove pipe and were just waiting until after the New Year. We heat mostly with wood stove heat and so it is a necessity. My husband had replace the elbow before and it was showing signs of rust. Nature intervened when a squirrel decided to climb into the chimney and fell into the rusting elbow, separating the pipe and knocking a hole in it trying to get out. We did not realize how rusted it was. My husband went to Hudson Hardware and bought the replacement section and was set about replacing when the whole pipe fell from the ceiling to the stove. Yes, much cussing ensued, and after buying the remainder of the pipe he has set about attempting to replace. This is not a one man job, and I am of no help. (Not by choice....) Does anyone know of someone who would assist him at a small fee? We are $$ strapped which is why he attempted it himself initially.
