His velocity is too low for a D1, most won't even look at him. The magic number for a RHP is 88 for D1 ball, LHP less, 84-86ish, but he will need to have something special or different in their delivery to get noticed. At this velocity he would, at best, be a situational reliever if he has a quirky delivery and gets a lot of K's.
What is his GPA and test scores? If they are high then I would go D3 vs D2. You will get more academic money for a high academic kid than athletic. At least on the west coast D2's tend to be lower academic state schools. (generalization, I know there are exceptions) NAIA is also an option.
Like LHPmom said, be frank and have him ask straight up where he is on their recruiting board. When you get down toward the later stages you have to be very direct and ask. Questions like "where am I on your list, number 1 or number 10. If you are below 10 forget it. You can't waist your time and most programs will tell you where you are.
Based on what you posted I would focus on options below D1.
