Technician course

Hi I am currently employed as a bar manager located in Leicester. Over the past year I have been trying to get into the drinks dispense side of the industry and finding it near enough impossible. I have contacted all the major companies out there such as T&J, Three Nations, Innserve, Everards and the list continues. I have also contacted course providers but no luck on the courses. Is there any other suggestions that you can give me? Thank you for your time Gurj Mann
