1.4 Btc needed For new Script @ 6.5%

Cause i need to keep all my bitcoins atm to keep the faucet running to not loose any visitors. reward is atm min 1000 satoshis what is very high! but with a mush nicer script i could attract more visitors!
i already have a stable income off 120$ a month so it will not take to long to pay back with a intrest off 6.5% or give me an suggestion
this is my faucet now http://coffeebits.be
as collateral i give my domain+hosting + script installed now (paid for 5 years)
