Horror is in my opinion, one of the hardest genres to work on, along with humor; because a lot goes into giving someone a genuine scare. Nothing can be hurried into, one must let the plot build, ket the readers familiarize themselves with the characters and, choose the perfect, unexpected point to actually create a confrontation. Apart from this, the plots are generally complex and must be backed by a lot of research which provides the narrative some substance.
Although I have never worked in the genre, apart from a few short stories a few years ago, I would love to be at it again. Having worked on several Ebooks and stories already, I am confident that I'll give you quality content. You may see the work I've done so far to affirm that I am worth my salt.
I have no problem with the $150 budget for 15k as long as the work is consistent and, I ensure that the final draft is the best it could be, no matter how many revisions it takes. I offer you a rich vocabulary, consistency and, effective communication. Past employers have always had an easy time working with me and have also appreciated the work; I am often able to create long-term partnerships.
Let me know if you're interested. My work will always be authentic, just like this bid. :)
