get a simple auto mechanic kit. using either 9 or 10 size tools, take off the side skirts. (this is necessary to take off the wheel well. after you take off the wheel wells, you will be able to reach the screws behind it to unclip the bumper. it may seem daunting and hard to do, but the only hard part is the clips. make sure you remember where everything goes back for when youre done.
(can anyone else input advice for the screws around the trunk and under the car if any?)
