In major metros in the USA $100/hr is entirely reasonable for someone who gets results directly. If you're performing a specific task you're very comfortable with, or will be on call, bill the full rate in 15 minute increments. If you're venturing outside of your comfort zone and/or providing soft consulting such as advice, discount appropriately. Likewise, if they'll be providing you work in bulk (some number of hours per week, or a long project), consider discounting fairly aggressively as well. Freelance hours (1099) are different than employee hours (W-2) from a tax perspective, so be sure that your income is equivalent to what you'd want to have as an employee at least.
