How do I find a co-author while protecting my rights?

I’ve compiled material for a book about the economic system for laypeople who consider economics to be a difficult and boring subject.

The book describes economic concepts in easy to understand terms. I believe the book is unique partly because it doesn’t focus too much on economic principles but rather examines the historical developments and political issues that have shaped the economic system into a system that benefits the few and does little for the mass of people.

I have written over 350 pages, (using Times Roman 12 point font).

I believe the book has a reasonable organizational structure and interesting content.

However, a lot of the material needs to be rewritten, edited, some material needs to be discarded, other material needs to be added, some material needs to be reorganized, etc.

So a lot of work still needs to be done.

Unfortunately, I’m not a writer and I don’t have strong writing skills.

To make matters worse, I’m suffering from neurological issues that have limited my ability to focus and work.

So I need help in finishing the project.

I placed an ad on Craigslist seeking a Co-author. I mentioned in my ad that I couldn’t pay the co-author but that I would gladly give him or her 50% of the profits, i.e., if the book made any profits. However, I didn’t receive any response to my ad, which is understandable since most people are looking for paid employment.

I therefore placed another ad on Craigslist stating that I was willing to pay $15 per hour for 80 hours of work. Although I would like to find someone who can review and rewrite the entire book, since I have been out of work for over 5 years – due to neurological issues – I don’t have the funds to do that. I therefore figured I could possibly find someone who could review and rewrite only certain, limited sections of the book.

I don’t know if my strategy will work, but my plan is to give the writer 80 hours of work now, see how this person does, and then give the writer another 80 hours of work later. After that, I will have to finalize everything on my own since I don’t have a budget to seek any further assistance.

In response to my recent ad on Craigslist, I’ve received about 20 resumes from people who have expressed an interest in helping me.

I would like to ask for your kind help regarding the following issues.

1. How can I ensure that the writer who works with me does not use some of my material and publishes it on his own?

Would I have to sign some sort of contract with him specifically addressing this issue?

If so, is there a sample contract that I can find on some website or reference book that I can use for this purpose?

2. If I’m able to eventually find a publisher for the book, would they have a writer on staff who could help with the writing?

At this time, I need someone’s help to finish the book and rewrite portions of it so that it will be in an acceptable form so that a publisher would be willing to consider it.

But since I lack strong writing skills and the writer I hire won’t be able to rewrite many sections of the book due to my limited budget, I think I will need someone else to review the material and improve it.

I would greatly appreciate it if you could kindly provide me with any guidance, advice and assistance.
