Not a good plan though, OP better find them in person instead here since no one would allow someone who's hiding behind the internet to trust their money on them. Without a reputation in the first place, it is considered as untrustworthy so people should be aware of that.
I think even if there is someone who already experienced in sport betting, there is no one would lend him 0.1 btc ($1280) because his bet could lose too except he will guarantee your money if his bet lose
