Is it possible that we (I&husband) do the flyttevask by ourselves so we don’t have to hire flyttevask bedrift?

So we will move out to Ski from Oslo. We live in a 42kvm hybel and my husband thinks it is better if we do the flyttevask by ourselves than spending 6000 to 7000kr for flyttevask since we are saving our money to raise egenkapital. But is it doable?
