Saving a Pony From a Meat Sale

I just rescued 3 miniature horses from this same kill pen (Moore's) in Lebanon, PA. There is a 17-year-old-ish very sweet paint pony mare I don't want to leave behind. Her deadline is Tuesday 3/5 at 8pm to ship to slaughter. I now have a rescue (South Jersey Horse Rescue) willing to take her in if I can help cover her bail from the kill pen ($640.56), shipping/pickup to quarantine ($150), 4 weeks of quarantine ($475) and also vet expenses. Would love your help to save this little pony and get her to this rescue.
