In addition to all the previous tier rewards, after at least three months of this level support I will negotiate commissions with a MEGAFAN. I only write stories I want to write, but I will try very hard to come to an agreeable agreement and write you a commission -- for an agreed upon extra fee (like $25 per 1000 words, which ain't nothin'). It is vitally important to me that I don't drastically change my output to cater to people with money, but I will reward solid support with extra focus, time-permitting. It may be as much as a year to finish a commission, especially if I have several commissions in queue.
A possible discount is available for simply commissioning a story continuation from an old series.
