@LakeAlto I second the recommendation to Ohio State. It gave my DS a full-ride back in 2010 but my students the last two years have gotten the National Buckeye and Provost or Dean scholarship. With those scholarships, it would put Ohio State at your budget leve. Be sure to apply early so that your DD could apply to the Honors College or Scholars program. Everyone I know who has done them really enjoy them.
Look also at Miami of Ohio. It is considered a “private ivy” (public universities small in size that are similar in set-up to the ivies). One of my students there is on a full-tuition scholarship. I really liked it when I toured it and it has both good liberal arts and engineering/sciences. I think it will be tough to get to your $20-$25K budget with private colleges since they usually run around $60 to $65K so taking $20K off the budget with merit will still leave you with more (like around $40K) than where you want to be budget-wise. One college that is private but good with merit for my students is Baldwin-Wallace. They have a special scholarship for OOS that really helps to get my students at that less than $25K level. Tulsa, Seattle University, University of Dallas, UT-Dallas have been good with merit. Smith and GW gave my students two years ago $30K plus a research stipend, but you have to major in a science or engineering. My student with similar stats just got $20K from Grinnell but again the total would not be $25K that you would have to pay.
Be sure to have your DD apply early action, I find the best merit is always given to my students who are applying early action. Since Georgia Tech is just across the border and you mentioned that your DD may want to major in environmental science and GT is a Stamps school, I suggest she apply there also. GT will invite 300 students to interview for Stamps and invite 100 of them to campus to do additional interviews before they decide on the 40 Stamp Scholars. Last year, my student made it to the 100 but was not selected as a Stamps Scholar, however GT did give her a $25k a year scholarship which really made GT affordable. Now GT has gotten a lot tougher to get into, but it does have Stamps and a few special scholarships for Florida residents.
