Replacing front bumper and headlight fixture do-able?

Recently I bummped into someone and due to only having liability insurance the repairs are on me. The car is still drivable but the plastic front end is all cracked and the left side of it that attaches to the fender(I believe this is the metal cover over the tire) came off of the hook and the hook is damaged and wont go back on. Looking at the unit I need to replace the part that hold the headlight due to it wobbles a little as well as the front cover. Was wondering if this is something I can do myself because it seems likes its only a couple of screws and clips. The airbags did not come out and the repair costs quoted are 10 times the cost of if I buy aftermarket pieces and wondering if this is a viable option.
