What I did at that age: computer training classes. Your friends are already familiar with a classroom setting, and probably have something they could teach to people who aren't computer/smartphone/tablet savvy. Think 'Intro to smartphones' as an hour long class at a common area in the local retirement community. This has three big advantages over a traditional job. 1. You set the schedule. So it doesn't conflict with school/study. 2. Excellent monetary return on time. $10 a head and a class of 10 people is $1k. It's a good deal for them and you. 3. Doesn't generally require a huge level of knowledge/experience like professional development or sysadmin type work. A less visible advantage, is that it broadens your network. All of your students will have your name handy if someone is looking for an intelligent IT guy. Also a great way to generate leads if you are doing house-call type IT fix it work. This of course depends on your friends maturity/leadership level. They have to be comfortable teach a class, and dealing with people on that level.
