What are you planning to do with the land and sheep longer term? Kill for meat, keep for fleeces/pets/ lawn mowers?
How much land do you have and is it well fenced?
I keep Hebridean sheep near St Cyrus, and could have a couple of unregistered ewe lambs or some wether lambs or hoggs for sale if they were suitable for your requirements.
Feel free to reply or message directly if you were interested, or fancied coming to have a look
