VA Buddy Letter supporting Migraine Claim

I need a templated strong award-winning Buddy, CO-worker, Supervisor, and Spouse statement letter created for a VA claim.  I will attach the link to the VA website and the goal of the letters are to provide witness statements to support a 50% rating.  These are just templates but I need research put into this to provide me the required letters.  I will attach examples from websites but I need an original template.

Link is a youtube breakdown on what information is needed
