How about doing something different to advertise yourself - has your IoW paper run a feature on what it is like to be unemployed, perhaps a diary format.....something well written may be of interest and attract a potential employer.
(ii) have you used family and friends to try and get an open door for you, at least to get you face to face.
(iii) experience before education and how that experience could benefit their needs (having done your research and been on line - have you tried asking their HR if you could meet someone for lunch to try and understand what they need better - a meeting where they should give you info, not the other way around, again to help focus your application.
What's your Facebook like - that sinks many candidates before they get to the front door, silly and embarrassing photos, stupid comments and opinions etc etc..........Remove it.
