This is a very common "scam" where a company will tell you your songs/lyrics are great and you then pay them to record a demo and pitch your songs to the "industry"
This is exactly the same approach as the "model agencies" that approach young girls in the street and tell them they could be models and they are "exactly the look they are looking for"...but they need to pay to have a portfolio of photographs done
This company makes its money from producing demos - I would not put
ANY value in the fact that they will "represent you" or "expose you to the music industry"
Their rate and quality of the demo may be OK but I would personally recommend that you walk away from any company that operates in this way
There are plenty of services out there that will produce demos if you pay them
I offer this service but I am very "up front" that I am offering this service with no strings attached and no promises that I will expose you to the music industry
I would obviously advise and help but if you want a song produced of any quality (even "Humpsy Dumpsy") I would do it for you and help you make it the best it can be
If you only have a lyric then you are also looking for someone to write the melody and music, which leads to discussions about sharing the writing credits and % splits etc.
I wouldn't get too hung up about this part though as the chances of a song from an unknown writer making a serious amount of money is probably less than getting hit by a bus!
If you want your lyric turned in to a song I would shop around and look for "demo services" - or drop me a Private Message via the forum and we can talk
