Some things are not meant for a diy deal. Its way cheaper to have it done than to mess it up. If the dealer messes it up they get to eat it. If a person has never done mechanics and engine work and doesn't understand what is going on real good they should not be doing the job, it gets expensive if not done right. Doing a job like a timing belt is not guess work, it needs to be pretty exact, you can't do very many mechanic jobs using guess work and thinking its going to be okay, if you don't understand how it works.

At 255k, my crank seal blew and coated the belt, tensioner and everything in oil. Since I've only worked on Hondas (Accords and Preludes) before my LS400, I gave it to the mechanic to do a big job like this. He even screwed up by not timing it correctly the first time and had to redo it. First time after he completed the job when driving away, I had no power when I eased into the gas pedal and the engine started sputtering. Within a block from leaving the shop I took it back and it took him another day or two to get it right. The second time he didn't even add the correct amount of coolant back and it almost overheated on the way home. I quickly turned around after 4 miles on the highway (luckily cold in January in AZ) and had him add more coolant.
I'm pretty sure it was his first LS400 TB/WP job but I got the TB/WP cam and crank seals replaced for 400, so I felt it was worth the risk and extra added hassle. He did drive me home twice when he screwed up so I think he ended up losing out on the job due to all the extra added labor and time spent. He basically had to do the job twice but that's the risk you take if you don't know what you're doing.

Pretty sad that a 'real mechanic' has such a hard time doing a timing belt on an LS. I'm a software engineer by trade and my first and only timing belt job done myself was on my LS and had no need to take it apart again after... if I were you I'd avoid that 'shop' at all costs, makes me worry what else he did wrong might be lurking around.

I have a feeling that he used the shop 2-3 doors down for assistance, they do 2JZ swaps in SC300s and crazy tuner performance upgrades on Toyotas. I might go to them if I still have the LS400 in another 75k miles and if I'm still in AZ.
