You say that like it's a big deal! For the money he's getting, he should push out at least 5 updates per year.
People who drops their hard earned money into his pocket should pressure him to hire an assistant. It'll make his work less stressful. He'll be able to work better and we'll also get more updates.
actually, the updates wouldn't be quicker when hiring someone, as L&P would have to take time away from working on AWAM to catch the person helping up, so the person helping knows the AWAM project as well as he does.
The daz files is a loaded thing on its own to learn, L&P will have a load of assets he uses that he needs to make sure person helping has access to, and then there is presets L&P probably made that he needs to explain what they are for. Also, there will be other daz related things he needs to make sure the person helping knows
He will also need to explain the complete full direction L&P wants to take the story.
Then on top of all that, L&P and person helping then need to come up with a system together on how to do updates, who does what etc. That is not something you just figure out instantly, it will take time and potentially a long time.
So all in all for the first few months at least, the work on AWAM would take even longer for an update to be finished, and I think it would be more like 6-9 months before you may see a benefit to someone helping.
I do think faster updates be a great thing for AWAM but hiring someone is not the quick fix you and others think it is.
edit* sorry for the short story I wrote but wanted to make sure I covered why getting help isn't really the answer.
