Why don't you list packages or fixed pricing?
Because I'd have to pretend I already know what your problem is.
I don't.

Every engagement is custom-scoped.
Chances are, neither do you. Not completely, anyway. Most organizations come to me asking for one thing and leave having solved something else entirely. That's because the visible problem is often a symptom of a deeper structural one.
I don't believe in selling predetermined solutions to problems I haven't diagnosed.
Every engagement is custom-scoped based on a number of factors, including organization size and financial capacity. I believe that good work deserves to span access gaps, and I do work with mission-driven clients on a sliding scale basis.
Our first conversation isn't a sales call. It's a chance to understand what's actually happening. If I'm the right person to help, I'll recommend an engagement that fits your situation. If I'm not, I'll tell you that too.
