Katie, Look at e-bay, that's about as cheap as you can find them. I just looked and they have a few and if you get lucky like i did, you might even find one the right color.
Paying 50 to $75 is not bad, But remember you will have a shipping charge of just about the same amount. So your talking around $150. Also remember 95 thru 98 will work for your car. AND that's not a bad price.
I also just looked in crash manual and it is $257.60 and that's not painted they come primed, so it would be better to get one off e-bay or someplace like that.
Now the problem is that when the bumper came off, what else went with it. There are a few parts in behind the bumper (which is actually called a bumper cover), and that all you get is the cover. SO MAKE SURE you have it checked out so you will have all the parts needed when it's going to replaced.
A little trick is go to a body shop get a estimate and when you get your copy it will list what is needed including if there is any more damage behind it.
And also another thing you will have labor costs etc... added in SO you will have around $350 in it by the time you buy it, plus installation and paint. Hopes this helps you out.
