Swapping an engine

Hi, I need a new or second-hand engine for a 1994 Ford Fiesta. I have found a second-hand engine and I am just wonderiing if its a major job for a mechanic to swap them over. Whats the procedure?
Thanks

94 fiesta, eh?
if its the same engine that the car origionally has, it shouldnt be TOOO hard.....gonna have to swap the transmission over, probably gonna have some wireing to mess with, hoses and fuel lines and such to connect, but other than that, i dont think a decent mechanic with the right tools couldnt do it.....
the Fiesta probably has a really small engine, and a fairly open engine compartment.....now if it were a 93+ camaro or firebird....god, they shove those engines sooo far back.....you drop a pin from above the engine compartment, no matter what, it wont fall to the ground! hahaha

BTW, your user name....Vedder as in Eddie Vedder of Pearl Jam?
