Looks like the window regulators are bad on both sides.
They are about $ 120 / each and takes about 1.5 hrs to replace each side.
Depends on the shop rates in your area it will be near $500 repair including parts and labor for both sides.

You need windows regulators. Check your local shop for cost.
