Is it a newer car with a plastic bumper? Just the plastic bumper damaged with no sheet metal damaged?
You can buy complete replacement pre-painted to your cars factory paint code on ebay. Buy a bag of clips too.
I have done this a couple times on different cars. Its not hard to do. Pop the old one off. Transfer any badges/grills/lights and pop the new one on. Usually a screwdriver, a ratchet and a socket plus the clips.
They will paint your bumper, let the paint cure for a couple days. They fold it up and shrink wrap it. They mail it like that. You will need to unwrap it and let it relax for a day or two before you try to install it..
The removal/installation itself is only a hour or 2 taking your time and drinking a beer
