I need a songwriter of mostly country music but im up for anything if anyone can help.?

I am a 17 year old guy and I love to sing play 5 instruments including piano and guitar. I actually won a talent contest for my singing, but I have tried a hundred times if I've tried once and I cannot complete a song that sounds decent. I am in contact with country singer Rodney Atkins and have expressed my longing to sing but he told me that the quickest way to make it is with original songs and so I come here and ask for help. If you will consider this I will post my email and I am up for co writing or a singing something I didn't write it is all fair play so please help and thanks.
