Introduce Yourself : entry level job in London by Helen Collens

Hello I am looking for a film/tv production job in London uk. I am looking for something that is entry level like a PA or assistant or runner etc as I dont have any experience but I am wanting to gain experience over the next year and a bit as from this sep I am going to be applying to do a BA degree at universities and want to get some experience before I start. Also I feel it will look good to universities if they see that although I dont have a level 3 qualification in film I am committed to doing film which I am and would love to get as much experience as possible. If anyone can help please let me know
