BTCPOP.co is great if you are an honest borrower.
I have borrowed many times from there and they offer around 30% APR on instant loans.
Altho you will need to build reputation there for bigger loans, do not assume you will get a 1BTC loan instantly funded for you.
If you are thinking about signing up, let me know and i will shoot you my referral link

yeah, please do. i'm looking for funding to hire an additional engineer for my project. it might not be enough for my case, but it's worth a shot
