Knocking noise from bottom end?

Hi guy’s I’m looking at 2004 sportsman 800. Now the owners family member was riding it and there was no oil in motor. So there’s a constant and really loud noise from sounds like RH bottom of motor.

My thoughts is its the bottom end and needs a full rebuild.
My question is has anyone had a shop rebuild one? and how much was it?

Cheers From Australia.
