Beloit can be really cheap. Has great FA. I’d leave that on the list.
Mt. Holyoke has aid for international students and you might find a home there. It’s a lovely school and their best FA can dip as low as $7K total payment from families. They also love international students are very empowering of women. https://www.mtholyoke.edu/ Georgeous campus. Also free buses to four other colleges where you can take classes.
You may want to try entering the two full scholarship competitions that I’m aware of–
Since you like College of the Atlantic, a similar school in Vermont (not Maine) is Marlboro. (https://www.marlboro.edu/ ) It’s a similar size and has a similar approach to education. Also the nearby towns, while not on the ocean as COA’s campus is, it’s in a gorgeous area of Vermont with cute towns nearby. Marlboro has a full scholarship competition here (this is last year’s prompt and I believe they are posting this year’s prompt soon. You can call them or email them to find out) – https://minds.marlboro.edu/
The second school is Green Mountain College – also a lovely school. Here is their full scholarship competition information – http://www.greenmtn.edu/sustainabilityscholarship/
