Okay, let’s calculate this. Tammy has a mix of skills that are in demand, but her experience is mostly in project management and account management. These roles typically pay around $40–$70 per hour in the US. However, her skills in business development and strategic planning are also valuable. These skills can command higher rates, but they're not as common in her skillset. Considering her experience and skills, I'll estimate her hourly rate to be around $75, which is on the lower end of the project management spectrum.
