Ref: Military Law (U.C.M.J.) Is there a source of legal assistance available in preparing the DD-149 for Discharge Upgrade?

Over many years now I have researched, obtained military records and prepared the case but need assistance in preparing (especially particular portions) of the DD-149. My separation from the Army has gone beyond 15 years which I understand requires the DD-149 for the presentation sent to the A.R.B.A.. I have discovered (and proof) fabricated military documents, multiplicity of charges and documents containing the signature of other than my own where my signature should appear. I am hoping to find a source of this assistance required as near to my home location as possible. I have had assistance for most of the investigative yrs. from the Department of Veterans Affairs in Chas., WV. I feel I am beyond their ability in assisting at this point due to the complexity of the evidence discovered.
