Sorry! I still need to make a proper commission information sheet!
In general my rate is $30/hour of work, with most simple to moderately complex pieces taking between 1 and 3 hours.
I rarely accept complicated commissions (lots of characters, complex environments, subjects out of my usual wheelhouse, etc.) because they're stressful to work on and take forever to do, and at the moment they're not worth the money to me and would probably not be worth the amount I'd end up charging to potential commissioners.
Feel free to contact me at ascalaphid [at] gmail with inquiries.
