Okay, let’s tackle this. So Nadia has 21 years of experience in graphic design, which is a significant amount of time. Her skills in Adobe Creative Suite and various design fields like illustration and interior design are also valuable. However, her experience is mostly in one field (graphic design), which might limit her earning potential compared to those with more diverse skill sets. Location is Laval, Quebec, Canada, which might affect her rate. Considering her experience and skills, I would estimate her rate to be around $125 per hour, which is below the average for a senior graphic designer in Canada. However, this is still a reasonable estimate given her unique combination of skills and experience.
