Based on the skills listed, I'm estimating Trevor's hourly rate to be around $125. This is a conservative estimate considering his experience in .Net and software development, which are in-demand skills. However, his lack of specific certifications or a high-level position (e.g., PMP with a large company) brings the rate down. According to the Bureau of Labor Statistics, software developers in the Baltimore area have a median salary of around $114,000 per year, which translates to approximately $55 per hour. Given Trevor's skills and experience, I believe he can command a higher rate, but $125 is a reasonable estimate based on the information provided.
