A moving company isn't going to touch any of the shit (vehicles, parts, tools, etc) that are going to be the most difficult or time-consuming to move.
Just to be clear - when we moved, all done by a big company (Allied IIRC), I had a whole basement full of tools, parts, scrap metal, etc.
They packed and moved all of it. It just added a lot to the cost b/c they charged by weight and some formula for packing time (yes, we even had them pack for us).
I didn't care b/c it was all covered in my hiring package. But in retrospect, we moved a ton of shit that should have just been tossed or given to friends. DEFINITELY take this as an opportunity to thin the herd.
They aren't going to touch the project vehicles though. I mean - they will, if you find the right company, but you (or somebody) will pay for it for sure.
Professional packing is amazing, awesome, and quite daunting later. They will pack anything and everything just as it sits in the room. They don't hunt around to find just the right box for stuff, or to gather things from different places to pack them together. Literally whatever is near together in a room goes in the same box. They don't really care so much if the box is full, just convenient and fast for them to get stuff in. We literally had a trash can full of trash end up in a box in our new house.
what this means is that a couple of guys can pack your house very quickly while you sit back and drink beer.
But it also means when you get there, you don't have a fucking clue what is in what box, and unpacking is like Christmas for 3 days straight.
