Hi and welcome.
The first thing before you get any animals you have to decide if you have the commitment.
This may seem obvious but no matter what the weather, how late you are from work or how sick you feel, depending on the animal they will take and hour to two hours of your day. Then there is buying food, storing food, carting water, fixing fences, finding a large animal vet and the paperwork you have to fill in. If you get fed up you still have the responsibility of caring for those animals.
If you are still keen I would try Facebook, there will be a smallholders page, join a group and try and network. You may get lucky and get a lead for your own plot but their may be someone who you can share with.
I did pig share with a local person, which we bought the pigs together and there was a contract, we shared the bills for the summer and then took them to the butcher. The reason why I mention commitment is no matter how lovely this person was, keeping the pigs was just a side issue to what ever else was going on in her life and a bit of a fad, and its not County Living , so I ended up doing most of the work.
So I would work backwards.Find your abattoir first, find your nearest animal feed place and do costing, register with a large animal practice, find out the regulations for keeping animals and the equipment you will need. Work out if there is no water supply how you would get water there.
By finding out all of this when you find your land to rent you will sound reliable. Good luck.
