Hi from the Borders
I agree with Rosemary, don't rush. A couple of pigs would be a good next step. Make friends with your farmer neighbour: many farmers are (often from experience) skeptical about smallholders ability to manage livestock: ask if you can come and "help" and learn lambing etc. from him. Once he trusts you he's more likely to be sympathetic about renting you some land.
Good luck, and keep us posted!
