I have about 13 years of investigating experience. I am a trained Archaeologist but I was terrible at it so I do not do it anymore. I am self taught in everything I am good at.
I am expensive, but still a bargain. Most online investigative services are subcontracted out so many times that the real cost is about $100 in paid fees to online services. I use these too but I can see patterns needed to tie everything together for you.
I can give you references. I can give you quotes. I do some things for free but there has to be a really good reason for it.
