As a creative writer for more than 15 years, I believe I'm the perfect candidate for this job. My expertise is in poetry; it's what I studied and the form in which I've been writing the longest (but I am open to novel-writing, too).
The length of my bid, 30 days, would be to complete a poetry collection with your direction (i.e. number of poems, subject matter). A novel, of course, would take longer, but those details won't matter unless I'm chosen.
My work has been published in local print media, but I am just starting in the business of freelancing, so please consider my bid being on the low-end an attempt to get my foot in the door, not a gauge of the quality of the work you would be receiving.
