That's going to be a tough find..
I have some 40mm wide 20" rims.. but nothing like that in 24"
Problem is that high-quality rims universally come with eyelets, and tend to be 14 gauge.
Nothing wrong with quality 14 gauge spokes, as long as the spoke flange is drilled accordingly, otherwise the hub flange is too large ( 12 gauge ) and the spoke shoulder/head will break over time.
What bicycle frame do you have that will allow a 3" + tire ?

2.5mm Brass washers under the head of the 14ga spokes reinforces the spoke nicely in the oversize holes. the brass is softer than the steel spoke but harder than the aluminum and deforms slightly to fill the extra space in the hole.
this is the proper fix for spokes that are loose in the hub/flange holes.

yeah i went through a heap of the stock 12ga spokes. Switched to DT 14ga with washers under the heads and haven't had a single breakage yet! (i did change the tyre too though)

I've been wondering the same thing, and came up with:

Surly Large Marge is available in 24", double wall with eyelets. Here is my non-electric built with 26" versions and 4" tires. I may have to electrify it someday:
The gallery is here:

The tires are Surly Endomorphs for off road use only. Their tread is shallow but widely spaced. Perfect for sand. But on the road, the rolling resistance is very high since the tire falls to the casing between every tread, it is like constantly rolling over small bumps. Also, at high pressures the tires turn into rubber bouncy balls, all the energy from all bumps are returned instantly with damping. The tires work great in single digit PSI where they flatten out and float over sand or snow.

Wow that chain ring is tiny. That look almost 1:1 ratio at your lowest gear. Is that comfortably ridable? I'm guessing it's good for around the block kinda riding.

Guess I shoulda explained it is a sand bike. I settled on 20x36 for front chainrings, I tend to not shift the front often with that big gap. I ride it on the beach in sand and on rocky washes that are hard to walk on. It allows me to get to secluded beaches even here in busy Southern California. I have a photo gallery of such a ride here:

That shows a previous version of the same bike. It would be fun to electrify on one hand, but it would limit me on the other. I like to ride close to the surf, and I can be overtaken by waves with water well over the hubs. It is fun, but tough on the bike, even without electric parts to think about.
Still, there are your big rims, they are 65 mm wide, available in 24 or 26". See them here:

Alex makes the DX32 in 24" as well. Very nice strong rim. And as far as lacing the wheels go, I recommend reading the Wheelpro book (http://www.wheelpro.co.uk/wheelbuilding/book.php). I don't think that 12ga spokes offer any useful margin over well built 13ga spokes for your application (you will be challenged by the lacing pattern - don't do radial, and try to get at least 2-cross). I would also recommend Sapim "Strong" 13/14ga butted stainless steel spokes.
Actually, RevDon's suggestions above are pretty good as well. I got some Nimbus 20" rims from unicycle.com that I really like. They are 44mm wide (!) and have Innova Road Hog 20x3" slicks beautifully mounted on them. For high-speed ebike use. The Road Hogs also come in 24"
