Based on the skills and experience provided, it's challenging to estimate an hourly rate. However, considering the skills listed, such as editing, graphic design, and community outreach, which are in demand across various industries, a rate of $50 per hour is a conservative estimate. This rate is lower than what professionals with similar skills in high-demand fields like tech or finance might charge. Without more information on Roberto's specific experience, location, or industry, it's difficult to provide a more accurate estimate.
