Fore me I prefer ramps. It's much easier than jack and jack stands.

I think most of us do it ourselves not just to save money but more of a satisfaction of knowing we're doing this right with care. At least this is why I do it.
Besides I really do not trust other doing it for me unless i'm there watching what they pour in to fill and how much oil they put in. One of our biggest problems is oil overfill which causes AOS to go out.

Do a survey to those that had this go out. I estimate half of them will say it's right after their oil change.

When I drain my oil i look at everything I have access to under the car. I also let the oil drain as long as needed. If I see oil still dripping I leave it alone and let it darin. Even if it takes more than 1 hr.

When I fill I use the same amount that came out, do a test drive and re-check my oil level before adding anymore.

I guarantee you that no shop will do this for an oil change. Time is money for them.
