I have a transcription service and pick-up cassettes and deliver work on a daily basis. I would like to eliminate that and receive the voice through the computer and sent reports securely to their offices

I am in the higher end of management in a specialized field and for family reasons need to relocate and find a new job. Eventhough I only put my home and cell numbers on my resume, I am finding people calling my work. How they had to research to get the number and leaving messages on my work voicemail can compromise my current job (which I obviously cannot afford to loose before finding a new one). How can I feel secure about sending out resumes while expecting professional practices and confidentiality to be respected?
