Soliciting your material through a producer may be the best way to get your material into the right hands.   If your material  has already been published, the producer is still invaluable. Some producers are also publishers that creates a different situation. The material you have published needs to get into the hands of the producers that will actively work to find the act or project to use your material. If a producers focus was only to find the act or project for your material, your material sometimes will be produce more quickly. If the producer is also a publisher, the focus may be to have a commission on your material for someone else to produce. You want to get your material in the hands of a producer that won't sit back and let someone else produce your music while they receive income on the publishing. This may happen in the situation of a publisher/producer. The publisher/producer has two difficult jobs. If your material is already published, and you submit your material to a publisher/producer who seems very excited about your work, you may have made a valuable contact to find an act or project for your material.

Many say there is a balance between the smaller production agencies and the larger agencies. The smaller agency may have more time and less material to focus to the acts, but usually this advantage is more than made up by the larger exposure to artists to follow up with your material. Most important is the excitement a producer will express about  your material upon submission.  Keep the material quality and keep creating new ideas for new songs. 

Timing is of the utmost importance. A right material in the hands of the right producer who knows the perfect act or project for your songs is difficult. Create new, quality material and submit to several sources. Don't expect immediate results from your first submissions. Don't wait, keep expanding your ideas in music and keep submitting material. There are many songwriters who look back and laugh at a song they wrote years back when they thought is was really good at the time. 

Most Producers and Production Agencies do not wish to receive unsolicited material. Call and ask about their policies of submission first. Most desire a cassette with about three well recorded songs and a lyric sheet with a self addressed stamped envelope with the package. Long bios are not what they are looking for. They are looking for material to suit the artists whom they are in contact with to perform the music. Results usually are generated in about a month.
