I've written a few songs over the years, need professional advice...?

Maybe Jack or someone can help. I’m not in the States nor even in an English speaking country.

I have few songs (lyrics and melody, but I’d like to emphasize the lyrics) which I think might be good (read: a hit). I perform and sing and know a thing or two about composing and writing, having studied journalism and working in radio for many years.

My question is this: how can I protect my songs, yet pitch them to someone (and to whom)?

Thoughts?
