Honestly, I've always been open for commissions, :) although I'm now at a point where my queue is basically completely empty. Meaning that if you're interested in getting a story written, now's the best time to hit me up! My commission info page has all the details, including pricing ($20 for 2,000 words/4 pages; +$10 = +1,000 words/2 pages) and such.
How big does everyone see a "page" anyway? I've seen some writing commissioners sell by the page. In my measurements (using the font/spacing/etc. I use for writing), 1 page is about 500 words. Curious what others see it as, so leave a comment if you'd be so inclined.
