There are hell lot of ways to get bitcoin. I have listed it down for you.
1. Trade bitcoin (it is the best way to get bitcoin)
2. p2p loans (btcjam and btcpop)
3. Sell service (if you know programming language, you can earn a lot)
4. Join signature campaign
these four ways are the best ways to get bitcoin for free. Though trading will need a bit of initial investment but other three ways are absolutely free and you can earn well.
i think trade and signature campaign is best option because loans is not really good and the OP dont have any skills to do ,
offering loan I think it's a risk as really life loan... you can get pissed without problem and lost a good amount of money
