I don't think the lower piece is separate from the painted part of the bumper? If it isn't, then you are looking at a repair of $500+ without the cost of parts. If the lower is separate, you can buy the part from a Toyota dealer and take it to a shop to get a quote. The dealer might even be willing to put it in. Assuming you wouldn't want to do it yourself. In which case, just look up a bumper removal guide for our car.
We here also have no idea how hard you were hit and there are no photos to judge from so keep in mind there could be additional damage behind the cover to the brackets, electronics, safety bar and/or foam, as well as the rear body panel. You might want to consider body shop / insurance options depending on your budget.
