I'm looking at a shingle hoist for getting wood up into houses but I'm worried it would be unstable or to slow. Has anyone tried it? What about an electric dolly where you could strap maybe 5 or 6 bundles to it. Also any easy way to get a hummel up without carrying. Trying to work smarter not harder.

This is where you make the money selling the wood at retail price.
I use a four wheel furniture dolly to move ten bundles or more at a time from the truck to a staging area next to the steps. A couple of dollies will help the truck to move on to the next delivery and keep a helper busy moving it all.
Hummel, break it down to small parts.
A machine can be so dangerous. My brother used a self leveling Pettibone to get plywood to the roof of a third story. Hardwood is heavy, you know.

I've used temp labor in the past for jobs that require moving boxes up stairs. Some installers are better than others and understand that moving the material is part of getting their job done. Others whine and want more money so when it makes sense, I just call in a couple of temp laborers for half a day and get it done. Bonus if you got a guy you can pay cash to.

Its all about the quote - make sure the client knows there's an additional charge for doing the upstairs work, and its included in the delivery and staging fee.
