Experienced Bookkeeper for Startups

My mother is a Certified Public Bookkeeper (CPB). She has decades of experience as a bookkeeper and controller and has been working with startups in particular for the past decade. Notable experience: bookkeeper for Segment (YC S11) for 2 years (eventually helping them transition to an in-house team as they grew). Also worked with Stellar Development Foundation and Sense HQ. We’re looking for an additional client. With an expected workload of ~1-2 hours a day, at ~$50 / hour. We’re NOT looking for: she does not do taxes.
