Spend $200 and hire a professional. A broken finger, foot, leg, or dead friend is not worth the risk.
But if you insist, I've moved smaller safes and here are some tips. Think like an Egyptian moving large stone blocks. Rollers and pullys.
Lots of golf balls under the safe.
Or steel pipes as rollers.
Or put the safe on a piece of carpet and pull the carpet.
Be aware of scratched wood floors, capinets, holes in walls, etc.
