Co-author wanted

Hello,

I am looking for a co-author to aide me in a book, I have been working on. It is about a certain musician. I have done all the research notes which, I can pass on to anyone interested. As it stands for now, I am not able to offer payment, but if the book does get picked up and published, there will be payment
for your hard work and co-operation. I have dedicated the best part of two years doing the research via various means(which, I found thoroughly enjoyable and fascinating)and I would like a like minded individual to see the project through. If anyone is interested, then please get back to me.

Thanks,

Danny
