If you are handy, invest in the service manual; remove the bumper cover (a good 4-6 hour total amount of work) carefully; push out the dent with your hand.

Now for the bad news...you may have damaged the styrofoam behind the front bumper-in which case, you have negated some of the crashworthiness of that bumper. You also have a good chance of cracking the cover when you push it out. You can fill it (not suggested) and then touch it up with paint. Also, you may see some white stress marks from where the plastic gave from the impact.

A new bumper cover will probably cost about $200-400 and then it will need to be painted and prepped.

Having this done by a reputable body shop (with painting) should cost between $800 and $1200 (based on what my Acura TL cost to repair for both front and rear covers).

Again, the key is that no damage was done to the foam and brackets.

Make sure to keep a container handy for any connectors, washers and screws.

This is not the job for anyone not handy or who hasn't been around cars for awhile.
