Beyond just the amount, I hope your project delves into the issue of effective administration and levels of personal choice.  For the first you can look at the recent bio identity cards and direct receipt of a basic income in rice in India.  Radical decrease in societal cost and increase in personal benefit.  For the second it is a question of where do I receive a basic income for - eg Tiburon or Temecula - and how is this decided and administered. For this consider the troubled hukou system in China.
