There are other very credible and ethical people in the music business that do this for a living everyday. I can fax you a list of recommendations or you can simply call me for their names and numbers. And, this is not a cheap process. There's an old saying in the music business. That's the question that everyone asks.
Songwriters love every song they've ever written.
Mothers love all their babies, too. However, not all of their children grow up to be cowboys. You must have a professional examine your songs, decide which songs are commercial and have a chance to get cut and then use their contacts to get to the people who make the decisions about which songs are going to get cut on their artists. If you have ever made a trip to Nashville, and went around to the major publishers, you'll get a really good idea, why you need to get someone who knows the ropes to do this for you. It's like hiring a guide to show you where the fish are in a huge lake.
