Short story editor

I'm looking for a short story editor to help me fine-tune my writing. My project is a short story in the fiction genre and I'm looking for someone to edit it for grammar and mechanics. Although I'm unsure if I need help with plot development, I'd like to hear what the short story editor has to say about it. This project could potentially be short term so I'm looking for someone who is experienced and committed. If you think you have what it takes to help me improve my writing, please contact me with your experience and rate.
