I've never sheared my sheep as before them we had goats and 1 was an angoran, I used to shear her with my needlework sissors, she was very good and stood still for the very very long time it took me, she looked like the poor dog from the specsavers ad on TV, I couldn't wait for it to grow back again as it mocked me every time I saw her in the field !!
:oand it didnt do my back any good either, I had to walk around bent double for ages !! So now its a pro every time, the chap we use we got through word of mouth here in France and it turns out he used to go to my secondary school in UK, small world or what !
Think if you only have a couple I would try to jion in with a neighbouring farmer would be a good solution all round
