I also have a bent front rim, and inquired about this at Brown Motor Works located in Pomona. As I recall, the cost was about $150 to have the rim straightened at this dealership. Brown Motor Works will out source this service. This price is removing the wheel yourself and bringing it in to them, otherwise the labor to r/r is another $125. When the service manager inspected mine, it was suggested to me to complete this repair when I'm going to replace the front tire.
Not sure what the condition of your wheel is, however if it's badly damaged or losing air, then you may want to get this repaired immediately.
