There are many different sites where you can use your funds converted into BTC for a loaning purposes. It obviously depends on what rate and interest you are looking for, but there are some options in between you can choose.
For example, Poloniex gives a great way to invest your bitcoin. You can just make an agreement to borrow your money for margin leverage purposes, as traders borrow the money while selling on alts.
With something like that, the rate is pretty decent and the whole investment is almost risk free.

Dont forget about using bitcointalk.org ! You need to remember that we have many people looking for a loan here, at "Loans" section in "marketplace" , I suggest you can go there.
