Instead of posting this up on Lulu and DiY, did you ever consider trying the traditional route and seeking agents and editors and etc?
Yes, of course I did! That's why I'm now on Lulu and DIY.
I sent the first version out to a dozen agents here in the UK and none were interested, although one did say that at 80K words it was too short. I then revised, edited and brought it up to 130K (plot, not padding). But still no one was interested.
I then tried US agents. None were interested, not even one partial request.
I then tried UK publishers. Out of the three that still accept unsolicited material, only one said they would read it. However, they then sent it back unread, saying the offer to read it was a clerical error.
So now I'm at where I am.
