Earth auger with outer sleeve?

The water you force down the the pipe, will wash the sand out the top.

You might even try a pressure washer with a turbo nozzle, add extra water to the water coming out the PW. Two hoses.

Cut notches in the bottom of the PVC pipe.

Bolt a handle to the 3 in pipe and move back and forth as you sink the well.

here is another spin on the idea,

Sand Points Well Drilling
the baisic way they do it is leave the bit in under the casing, (for some reason they removed there directions on the well drilling),

Attached is a drawing of a sand bailer we made and used to put down wells near Wichita KS. I hope my drawing is good enough so you can tell what it is. We were in sandy country and only put down cased wells. This could also be used with a sand point but I think you would need to leave the casing in the hole. We would use an old conventional hand twist auger to get to water. Water was anywhere from 10 - 20" depending on the elevation above the river. At that point we would insert the casing. (we generally used 6" PVC.) Prior to inserting the casing it was scored with a hacksaw for the perforations. A platform was made to clamp to casing to stand on. Our weight standing on the platform while raising the bailer up and down would cause the casing to go down while filling the bailer. Casing was cut to 4- 6ft lengths and was glued as we went down. It was amazing how fast this worked. We liked to get about 20 ft of water in the casing before we stopped going down. More important, we liked to get to coarse sand or gravel so our casing did not sand back in as water was drawn from the well. An A-frame and pulley system was helpful, but we put down a lot of wells before rigging the A-Frame. The well in my backyard was 60 ft deep and we hit solid rock at that depth. My well had about 45 ft of water in the 6" casing. A .5 HP submersible pump would not faze the water level in the well. I now live in eastern KS. and the rocks prevent this type of operation. I sure miss having all the water I want without paying the sewer tax on it.

I got a bit off suject on my last post. We made a auger/digger with a pipe outer sleeve. It was patterned from the old hand turned augers and worked pretty good in sand. We made an adapter and turned the auger with a rigid power threader. It was easier than the hand turned one, but a lot of our wells were put down where no electric power was available. Seemed everyone wanted a well for their garden on the river.
