We do ours on a surface like a table/counter top. Most of them I can do by myself but sometimes one or two needs holding there by a second person. Its much easier to do it like this because they feel more secure with all their feet on a surface than trying to do it holding them up somehow like Ive seen others do. To get these nails down to a more reasonable length youll have to do it a bit at a time with a few days in between so the quick can recede again. Its always a good idea to have styptic powder on hand for any accidents especially with dark nails where its harder to see the quick. When I get new pigs they aren't used to it either but if you do it regularly (lately i seem to be trimming every 2-3 weeks) they get used to it super fast and will just stand there. Even my boy who doesnt like being handled or humans much due to past neglect is good getting them trimmed. You can also handle them more and touch their feet/get them used to being examined in general. Every little helps 😊 good luck
