I also want to start a songwriting company. From what I have gathered you need a studio and a good producer where you can work on the songs which eventually become demos. To start a sngwriting company, you need as many demos to create a pool where artistes can shop, or from where you can pitch new song or album ideas to. I am still trying to learn about the business and publishing aspect songwriting. Tell me what you think
