Stake a BR?

Anyone know of an efficient way to get backers to stake a starting bankroll? Including ways of finding investors, explaining the proposition and the details involved, distribution of winnings and losses.

I'd like to begin playing at higher limits than my lone bankroll permits and I'm trying to accelerate the slow grind of table minimums. If I could add some funds to my existing bankroll, than I'd be able to make higher top-bets and risk only a fraction of BR.

All help is deeply appreciated.
