You probably have a fair chance of working for a farmer - look on fwi jobs - there's generally plenty of arable jobs etc which often include a house.
Owning it yourself though, that will require alot of initial capital (land, machinery etc). If your quite happy working for someone, go for it - a NDA would be good to have for working for someone - have a look on the jobs section anyway, you will find alot out on there.
My first job was through shooting, i started lambing for a farm etc, now i work there occasionally but work for a large estate - i did this by ringing them, getting wor experience and after that finished they offered me a job.Im still there now.
Also, even though the dairy industry is on a slight slump - if you want to go into dairy, theres some good jobs as herd managers etc.
To be honest, get work experience, it will teach you alot!
