well, I had a chat with out neighbour who self-published a book a few years back.
He told me that self-publishing is the way to go when trying to get a niche-book on the market.
You have total control of every sale and you can make a profit.
If you go through a big publisher he said you get about a buck a book...not my cup of tea.
If you break even he told me ; then you are doing well. :(
So, it looks like I'll be going through the same place he got his book out of and it will be on the market by summer!
