Swamped... yea, I have it from Dan himself.... We last spoke Sunday night at 10pm Eastern time. He doesn't hire just anyone. Backlogged... Unaware of any, except one case here that I believe involved a component failure and the owner has previously explained here.
I have found everyone there very helpful quickly via phone, text, or email.
Value doesn't = the cheapest. (although the "H" folks are out of my ballpark at least)
If I didn't live 2000+ miles away i'd have Livernois install what I bought from them every time!... and get a custom dyno tune every time.
