Okay, let’s tackle this. So Karen has a broad range of skills, including architectural design, project management, and sales management. While these skills are valuable, they are also relatively common in the interior design field. Location is Honolulu, Hawaii, which is a desirable place to live but may not be as competitive as major cities on the mainland. Considering her skills and location, I would estimate her hourly rate to be on the lower end of the scale. A common range for interior designers with similar skills in the US is $75–$125 per hour. Given her experience in project management, I would estimate her rate to be closer to the higher end of this range, around $100 per hour.
