- a documentation set$6,000
For a documentation set, the quote is $6,000.
To take home $85,000 after $9,000 of costs and 30% tax you need to bill $134,286 a year. At 24 billable hours a week for 47 weeks that is $125 an hour, $950 a day. Anything under that is a pay cut you did not agree to.
Technical writers at your level day at about $900; you sit inside the range, so quote it without apology.
A documentation set runs $2,000 to $10,000 and takes about 40 hours of your time; at your hourly that is $5,000. The number is the higher of the two, because the client is buying the outcome, not the hours.
A retainer is the month, not the hours: a set scope, paid up front on the 1st. It is priced about 20% under the same work bought one at a time, in exchange for the certainty; three months minimum, or it is not a retainer.
