Looking for a job: Veterinary care assistant

Hi I am posting from England. Myself, my partner and our 15month old are wanting a fresh start when our property in England sells and would like to use the money to live in Spain. My partner has had quite a few trades such as furniture installer, estate agent, and labourer so willing to do any work. My farther and my grandparents live in competa so I am very known with the surroundings as I've been visiting every year for 17 years. How can I get job advertisements sent to myself? And what do we need to know? 

Thank you!
