why don't you just export your services via export list feature? You can export to a nice CSV and then open in your fav speadsheet software and sort, etc. etc.
I personally would not suggest you dick with any services unless your 100% confident in what they do, and how they interact with other services, etc. So you here asking tells me you really shouldn't be dicking with them
Now if your interested in delayed start up of things, take a look at the free software http://www.soluto.com/
gives nice gui to work with showing you how long each thing adds to your startup, what others do with the service/application/etc.
But to your exporting your services via scrolling screencapture -- here this is much better way to do it
