Okay, so Andrea has 32 years of experience in the landscape industry, which is a long time. Her role as owner of Landscapes by Andrea suggests she has a high level of expertise and possibly some entrepreneurial skills. However, her education is in Architectural Studies, not horticulture or landscape design specifically. This might limit her earning potential compared to someone with a degree in horticulture or landscape design. Location is also a factor, as Pittsburgh/Washington PA might have a lower cost of living and doing business compared to other parts of the US. Considering these factors, I estimate her hourly rate to be around $75, which is on the lower end of the scale for experienced landscape professionals.
