Make these debt instruments trade able, issue them with an annual coupon of 30%, and the market would bid them up to likely 15% or 10%. 

Victims here would turn into investors, who would likely see an instant PROFIT.

This would also give you a means to issue more debt, after you know your cost of capital (that the market is willing to lend to you at) and allow you to invest in security/marketing/etc.

(To understand how this is likely the guaranteed outcome, one would need to understand how bonds move inverse to interest rates.)
