Pre-reader needed

So, as it says on the tin, I'm looking for a pre-reader to give solid, detailed feedback on plot, character development and world building. I don't need my ego stroked, but if the limit of the feedback is it's great/sucked, that doesn't help me. I need someone who can articulate, in depth how they are/aren't enjoying the overall story, the world the story is told in, and the characters as they interact with each other.

While being able to review spelling/punctuation/grammar is a plus, at this stage, It's not what I'm looking for. Right now, I need to get a sense of how the story is progressing from a narrative, not mechanical build up.

This story contains the following, so if these bother you, you know:

Consensual sex of both a homosexual and heterosexual nature.
Realistic depictions of violence of both a 'modern' and 'fantasy' setting.
Historically accurate depictions of Irish folklore about Fae
Frank discussions of the 'N-word'
Characters in interracial relationships and frank discussions of the difficulties of same.
Assault based on racial and sexual prejudice and the aftermath of it.
Good parenting (I know, it's rare...! :D)

Above all the successful applicant (my goodness that sounds conceited!) MUST be able to respond quickly. This story if evolving rapidly (21,000 words in 5 days) so detailed but RAPID responses are a MUST!
