Use search engine for someone near you in your region that does downgrading, I know there is couple threads made offering services for cost in USA and Europe
Just run search for " downgrade " and you should be able to find what I'm talking about ^_^
Hope you have success with it and bring many new things to scene ^_^
Best of luck and looking forward to what you bring to table.
