Really for only five sheep it would make more sense to get some handshears (buy double bowed ones - easier to press), I actually use dagging shears on mine, as they fit my hand better.
I handclipped my flock of 20odd by hand last year, did about three a day, do the belly with sheep on their bum, as you would do feet, then put halter on and tie into corned of two hurdles, and off you go. As long as the fleece is rising, it should be easy to do. You may not get the fleece off in one piece, but I wouldn't think you are trying to pay off the mortgage with the earnings from the WMB....
It is also so much more peaceful, the electric ones make an awful noise, and are actually more dangerous for both you and the sheep. Have some purple spray ready. Oh, and if they pee on any cuts on your hand, it stings really bad!
