If you know someone that runs a small business or whatever, ask them politely if it would be ok and tell them expect a letter asking for a referance if you are successful. Tell them what role you are putting yourself down for and the description your going to give (or just give them a copy of what you wrote.) Should be absolutely fine. Make sure you don't **** up on the dates though and memorise everything properly before any face to face interview.
Second option is, find a business that has shut down, there are plenty due to this recession. Give that business name and address, write whatever you want for job role/description. For a reference they usually ask for last employer and 1 other reference. Inform them that the business has shutdown and you dont have any relevant contact info for your manager and provide two different references.
Good luck, its hard to get a job right now.. and don't feel guilty about it. The employers should feel guilty for not giving young people a chance, the bastards. You have to pave your own way in life, nobody is going to do it for you.
