How to Clear Rubble and Stones from a New Garden?

Hey everyone! My friend just bought a new build house and is planning to tackle his garden soon, but it's full of rubble and large stones that he needs to clear out. He mentioned he might just remove the top inches of soil, which doesn't sound like the best plan. I suggested he consider using a rotary soil sieve or a general big soil sieve to keep the soil and sift out the rocks. After that, he could bulk buy compost or topsoil to prepare for leveling it out or starting a garden, but he's looking for any advice or experiences others might have. He's eager to get this done since he has a little one on the way! Also, he's open to renting equipment to do a proper job.
