Anyone near Somerset/Dorset that can Pinion????

I have a Carolina Duckling that needs Pinioning, (think thats how its spelt) I have never done this before and am not sure i am confident enough to do it. Can anyone help please.

I could but was recommended by the man who gave me the eggs to pinion as you have to clip every moult otherwise.
All my other waterfowl have been done but these were done before i got them.

Yeah i know it's only one side, just don't fancy doing it meself lol although i have been told it doesn't hurt, just don't want to do it wrong.
Vets it is i think!
