i doubt you will get a loan without collateral, but your account might be worth around 0.3 btc
The account is worth only 0.15 at most as a collateral as the lender should be sell it at , at least 110% of it immediately.
And OP you seem to be a honest guy( As far as your speech is concerned) but no one will be willing to give that loan without some "solid" collateral, but if you had some trust ratings people would be more willing but even that, seeing there are a lot of trusted accounts being sold in the market, I don't think you will be able to make this loan here.
And maybe if you haven't actually tried much trading before, do it with small amount, you will see its not always a win-win situation, you may even lose all of it, what will you tell the lender then(if you won't completely dissapear that is).
As for the amounts you will be repaying, you can make it your self from signature campaigns here, or maybe do something for bitcoin in exchange for your skills.
