Have you called any landscaping or excavation material places?
I had my washed river sand delivered on a dump truck from a place that also does mulch, compost, bark, and that type of stuff.
I like to use SEMI deep litter method... in other words, build it up with lots of natural materials like the forest floor. I use grass clippings, used shavings, hay, leaves, pine needles... adding some fresh stuff all the time because it is a process to keep it built up.
I say semi... because I remove whatever droppings I can. It may not be needed, but my choice.
I have sand, and use it as a base. But whenever the rain came the edges of my run stunk something awful. Since building up the more natural sponge (springy) like forest floor, NO smell around the edges when it rains... and I'm in the Pacific Northwest, so that can be a lot.
The sand was like a barren waste land with lots of dry poo dust floating around if you try to use the kitty litter scooper so many are fond of. There is no invite for beneficial bacteria in a barren waste land. But the semi deep litter invites good bacteria and bugs to come thrive and break down the organics. The sand in my coop got a layer of hay, mostly to soften the landing of birds coming off roost. But eventually sand becomes just a bunch of nasty dried out poo flecks.
This is of course MY take and suggestion. I realize we all have different environments and set ups. But I cannot recommend sand, even though my initial research pointed me that direction and I spent probably $150 on it.
Good luck finding what you really like and works really for you!
I do remember them using sand... but stock numbers were always low and cleaning usually included some hosing down when changing the water that will never happen inside my coop to wash the poo juice that stays behind out.
