Advice with sponsorship...

Hello everyone.

I recently auditioned to go to the USA over christmas and new year as part of a tour visting some of the more outstanding dance and singing workshops in LA and NY.

The good news is that i got in...the bad news is that i now have to pay for it.

Does anyone have any handy hints on how to fundraise some extra cash to help me...and im intending on writing to millions of companies for sponsorship.

Is there anything that you would recommend i include or exclude in that so very important letter???
