Hey man i'm not sure if you have looked into it, but have you thought bout going further with another math degree by chance? Obviously in today's professional world the more degree's you have the better it will look on your resume/get you prepared for a master or PHD. Just a thought I would highly recommend checking out different websites that show different opportunities in regards to careers in math like http://www.maa.org/careers/ which is a site that lays out multiple career options for you after you complete you degree. Another link I would check out is http://www.onlinemathdegrees.org which is a site that shows exact details of quetsions you might have about degree's how to get an online degree, salary questions etc. I know the GRE is important and I just thought this might be another option for you as well as you continue on with your education.
best of luck!
