Screenwriting

I am writing a screenplay and am about half done. I have a three page synopsis of the first half and would like someone to read it and give me five new log lines for the entire story. You would plug the new plot points into what I have written, I will re-write that and you would totally write the final three pages of the synopsis. You see it is somewhat of a blend between cyber crime and romance and I want more cyber crime. Tell me how much that would cost.
