Paul, sad to hear of your dilema, hope something comes up for you soon.
Just in case, she'll taste lovely tho (folks often say the best meat is from a 1st time sow) If you're concerned about "waste" beg/steal/borrow a sausage machine - the whole pig can be sausaged, you'll be amazed how many "friends & family" crop up to purchase some lovely, free range products, think amazing chops, honey glazed ham
If you've got any left, it'll freeze for up to 6-months (if
)
BTW - 18-months is quite an age to go to the boar for the first time & I also don't wean mine until they are at least 8 weeks old.
Try ads in your local feed merchants, farming paper, free ads etc for a bit of land - you could offer an environmentally "land clearance" service
Maybe someone on here can help?
Good luck, hope it goes well for you.
