I am a private contractor for the US Navy through NDI Engineering. I have worked for them for six years now and I can honestly say that there is not one part that I would consider difficult. I deal directly with the base I work out of ( I work from home). I send in my time sheets and monthly reports as scheduled to NDI. I have only gone to their office once for an initial meeting. Their office is far from my home, but I pick up and drop off work at the base, I enjoy typing so this job fits me perfectly. I put in six hours a day, five days a week. Evaluations are coming out soon so I could provide a copy to show my job performance. Dorothy McGraw.
