Answer:
The best way is to take a skydiving course at your local dropzone. There are several options, but if you are looking just to do a single jump, then a tandem skydiving course is definitely recommended. This is where you are strapped to an experienced instructor and they operate the parachute.
Typically, you will jump from anywhere up to 15000ft and enjoy speeds of up to 120mph. This takes around 50 seconds of freefall before the parachute is opened. A further 3 to 4 minutes of canopy time under the parachute takes you back to the ground.
You can also get your skydive filmed and photos taken by an experienced cameraman.
There are some restrictions to the sport such as age and weight. Many centres will not take anyone over 100kg's and will require a medical form signing once you are over the age of 40.
So the answer is, do an internet search and find your local centre.
