I am biased towards Crum because I got my start there this summer, but just because you didn't start well at Grove City doesn't mean you need to change worlds entirely. Right now, you're in a conference without any other human coaches, but there are plenty of more active conferences that may be worth considering. Active conferences are more fun, and if you have solid coaches in your conference, you can sometimes learn a lot from them.
One good choice may be the Freedom Conference, where jsajsa has built a perennial power at Delaware Valley (two-time defending champion, four straight Final Fours). I'm sure there are people here you could really help you out. It looks to me like
King's would be the most attractive option there this year. Run a motion/man, third in their division this season but only graduating one player, so you can have a small recruiting class to start out as you get the feel for it. Next year, they'll have six open scholarships (which is about the max class size for recruiting without things getting way out of hand), so you'll be able to make your mark.
Another decent option (although less full) is the ODAC. West Virginia is a great place to recruit as a D3, because they have a ton of D2 talent that can drop down to you and only one D3 school local (although people certainly swoop in from Virginia, Pennsylvania, and Ohio. I even come into West Virginia from Tennessee).
Bridgewater is right on the WV border and runs a flex/press, which is a pretty good combo. They do have six seniors this year, so you'd recruit a lot right away and you might struggle your first year.
And, of course, I can't get by without mentioning my own conference, where I got my start, the Ohio. This is one of the most full conferences in Crum D3 and definitely has the most trash talk. Most of the guys know each other in real life. They don't know me, but they're cool anyways. Sadly, all three available teams in my division run a fastbreak/press, which is not a good combo for someone starting out, but you could switch to say, Flex and Press easily enough in year one.
Muskingum is probably best set up for immediate success. They are graduating three seniors and have six juniors.
If you have your heart set on Allen, the Centennial, Great Northeast, Minnesota, NESCAC, and Iowa Conferences seem to be the most active (I have a team in Allen D2, so I just briefly checked coaches corners).
Nebraska Wesleyan looks like the best opportunity to me out of those. You're the only D3 school in your state, and I've always wondered if it's close enough to pick off some of the famously talented Colorado recruits.
Hope some of this helps. I tend to be long-winded. If you have any questions, just ask.
