My thinking may be wrong but I'll tell you my angle and you might be able to make better suggestions...
First I already have 2 books published but with nothing exciting in the way of sales. I have a third book in the pipeline.
However as it is in the self-help genre I thought I would look at selling it as an ecourse, because I think I might reach more people that way and make more money. So I would basically send them chapters and worksheets and not worry so much about traditionally publishing which, let's face it, doesn't pay. I think I got < $1/hour for the time I've put into my books.
A lot of people do this successfully - here is the link to the article from AW that I was talking about. Uh oh, can't find it but it was about a week back (maybe last week's newsletter, or the week before). Someone wrote about Julie Fast of Bipolar Happens and how she sells a lot of product electronically.
I'm interested in your writing, I thought you wrote fiction: fantasy & or erotic. Do you also write NF? I'm not familiar with Blackwell but I'll look into it. I do recall that you are from NZ
you were one of the first people I met when I came here. I was looking for help getting my books on Amazon but you have to be a US resident or have US warehousing.
