Please see the changes in contract terms, billing rates and days rates.
Engagements have a minimum $5,000 retainer and then a $375/hour billing rate for work done. The retainer is credited to the last invoice at the end of the engagement.
Work done outside of a retainer based long-term relationship will be billed at $500/hour with an estimate of total hours and costs at the beginning of the assignment. A deposit equal to 50% of the estimate is required before work begins.
Speaking and teaching engagements carry a day rate of $5,000 or $3,000 for a half-day.
