Installing pump set for a bore well

Need advice on installing a pump set for a bore well


We have drilled a bore well 8 months back, which is around 480 ft deep, but we did not install a pump set because of loose soil till 200 ft. To put a casing till 200 ft would have been expensive. This week, we did a video scanning of the bore well and noticed a blockage at 240 ft,  but there is water in the bore well from 55 ft as per the video. We are now confused whether to install pump set til 200 ft or just leave it.

We need suggestion from experts to take decision. Seniors, could you please respond.
