Critiquing service for short story.

I have written a short story in the horror genre. This is my first serious effort at creative writing. The length is around 5,000 words. I have edited and revised the manuscript numerous times, and I believe it is now ready. I am seeking a literary agent or literary consultant to offer me a confidential critique.

I am serious about writing, and have synopses for another twenty stories and several novels, across different genres. I want to start in the right way and receive expert advice from the beginning.

I am looking for someone who can offer me honest and brutal analysis. I need a written critique covering plot, characterisation, style, etc. I would also appreciate the opportunity to follow-up and discuss any points I need further help and clarification on.

This is my own original work, so you need to be trustworthy. Ideally you should be able to provide me a sample of a critique you have completed recently.

As this is a short story only, I have budgeted accordingly. I hope this is acceptable.

I would prefer English-speaking bidders from the UK or United States only.
