Hell of a lot of work if you want to make a site….? Being a org.uk can’t see it would be worth the effort…. End user unless they already have a site on a worse extension can’t see they would think it worth it …. Think the market having plenty of good free ones and org.uk kill it…? You could try specialist translator companies that do import/ export documents etc but unless they were English firms (which limits your market a lot..?) Think non UK firms would either look for there own cctld or tld... might get lucky and get a few hundreed but think its a big might
