These days YouTube is your friend, you can find tons of videos on changing your own oil there. Might even find one showing how to change oil on the exact kind of car he has.
Between cars often sitting so low and figuring out good jacking points, I rarely even try to jack cars up to change my oil anymore, I use homemade ramps with a couple thick boards and bricks. You don't have to get the car too far off the ground to get at everything.
It can be a messy job so I always do it in my driveway rather than in my garage so I don't get oil on my garage floor. Wear latex gloves and make sure to have a bag of kitty litter handy!
