Based on Jennifer's skills and experience, I estimate her hourly rate to be around $75. Considering her language proficiency and certification, she may be able to command higher rates in industries such as international business or government. However, as a communications professional with a degree from the University of Pittsburgh, her rate is likely on the lower end of the scale. For reference, entry-level communications professionals in the Chicago area may start at around $50-$75 per hour, while experienced professionals with advanced degrees may earn upwards of $100-$150 per hour.
