They are already selling it as a download and have offered me only 25% in royalties. If I don't like their work they said I have until March this year to write my own and they will sell my workbook if they like it. In the mean time they said that they need to continue selling the download in their catalog because it is advertised until August this year. My story has been advertised in their catalog as Best Seller for about 3 years and they have not have let me know formally. I found out because I happen to get the catalog.
Do I negotiate with them myself and ask them to give me 50% royalties? or do I have my lawyer hear what happened and write a letter for me at 300 dollars per hour?
