Would like some good advice?

well me (natasha baxter) and my friend (sophie pritchard) have been singing together for quite a while we started as a duo, we write alot of stuff as we both play guitar, when we complete one of our songs we'll play them to our friends to get their opinions on the lyrics and what they think about the song in general and like they know most of the songs we've written and always sing them, so they must like them. Well we are getting our demo made in January and we're putting tracks on it what we have written, i was just thinking should we like get in contact with the labels before going there with our CD or should we just drop it off there. We don't want to send it because we want to take the demo to every label ourselves! Thanks x
