My vet will usually do individual doses for many things, but because of the opened shelf life of Heptavac, they'll only do whole bottles. Medic Animal sells the smallest bottle (25 doses) for £24.60 including special next day delivery. Where abouts are you, arwelcoed? There's a sheep breeder just up the road from me He lent us his trailer to take our boys to slaughter last month and I was going to ask him if he had any spare. He has quite a few sheep though so not sure if he will. I might ask him anyway when he's planning on doing his ewes.
