Sponsorship requires a verification process that is easier the more corroborated information the sponsoring member has on the requestor.
If you don't know another ISC2 certified person you work with, I think your best option would initially be to join a chapter locally to you and have a face to face with a ISC2 certified member.
Falling back, let the community know where you are and I think someone can suggest somebody in your locale and put you in touch.
Worst option PM someone here and ask if they can sponsor you virtually(between you an me I think there might be an auditor or two in these forums, and those guys just love questions).
Thanks, yes indeed. I am located in Grand Rapids, Michigan area. I will go as far as to Chicago to get a sponsor if necessary.
The endorsement process online allows you to select (ISC)2 as your endorser. Someone will be assigned to review your resume and contact references to verify experience.
