Nice idea. I especially like the <40 hour jobs only - makes estimating much easier. Also, the $100 fee for projects to enter weeds out the low-ball projects that want 12 hours of work for $50.
@rpwilcox Yes, that requirement is taken from our personal experience / preferences. We like contract work because it's varied and interesting, but we don't want a long term commitment that turns into a full-time job.
