Age and Salary

I am a 40 year old male making a career change. Soon I will be graduating from Comm. College with an Associate in Networking. I have gained my A+, CCNA, MCSE and CNA. I have no practical Networking experience but I do have 14 yrs. experience in Electronics. I fear that my age and lack of experience may hinder my job search and compensation. Does anyone know what the market is like for a “Mature Rookie” and what the starting salaries are for the Baltimore/Washington, D.C. area.
