Okay, let’s tackle this. So Sean has a CPA certification from the AICPA, which is a well-respected credential. His skills in financial accounting, Generally Accepted Accounting Principles, and information management are in demand. However, he has limited working proficiency in Spanish, which might affect his earning potential in certain industries or locations. Considering his certification and skills, I estimate his hourly rate to be around $75, which is a reasonable rate for a CPA in Boston, MA. This rate is slightly below the national average for CPAs in the US, but it takes into account Sean’s limited language proficiency and the local market.
