Your first step is determining where you are shipping and/or selling your product. Interstate is covered by USDA FSIS, in-state may well be covered by a state food safety entitiy.
Go to www.usda.fsis.gov/ and search for "Grant of Inspection". There are multiple program requirements (HACCP, SSOP, recall) that must be available. There are also physical requirements around an on-site dedicated USDA FSIS office. You will also likely undergo a Food Safety Assessment (FSA) where you will have to review your programs, procedures, forms, and supporting scientific information. Depending on your process and HACCP category(s), you will have an inspector on-site either part or all the time that you conduct a covered process...which you will have to pay for.
Dig deep and go slow. It can be a cumbersome and frustrating process. You might consider contacting the USDA FSIS District office that covers your state and ask if they have an EIAO (Enforcement, Investigation, and Analysis Ofifcer) who can provide outreach servivces. Search for "District Offices" on the saem website.
