From someone who has done this recently (UT Chattanooga in Knight), you are looking at nothing higher than 1 or 2 star guys in your first year or two. You can certainly send some phone calls out to guys ranked higher, but in all likelihood they will reject you. The prestige difference in DI plays a much greater role than in the lower divisions. I'm not saying you can't beat someone a grade higher, but it will cost a lot of money. Competing with big 6 teams at this point is pretty much off the table because they will have a huge money advantage on you.
You've made it this far so you must have some semblance of knowing what you're doing. Don't try to reinvent the wheel. Recruit for potential, and in 3 or 4 seasons you will get that prestige up into the C/C+ range, and then you can start getting some real recruits.
