Earlier quoted context omitted.
Quoted daily ("Work is on a time and materials basis. Rate: $2,000 per day."). Invoices will typically cover a few weeks of work, depending on the tempo of your engagements, your relationship with a customer, etc.
This has to be regionally dependent. Around here there is no way you would get $2,000 day for web development. Best I have ever gotten is half that, for a one-day "emergency" engagement (i.e. drop everything and help me).
Contractor = 2x permanent employee Consultant = 3x Contractor
So $2k a day sounds on the low side to me but perhaps it works if you're talking 4-6 hour days.
