What’s the GPA? What’s the desired spend ? Where are you and how flexible are you geographically.
What major ?
You start with what you have and go from there (test score etc).
You can start now so you can buikd an initial list and make visits to see if they might fit.
Also, depending on where you live, there are various shared state programs - in New England, the Midwest, West Coast which includes Utah and Colorado. The SE too.
These programs, if you can access one, offer large discounts. Some, like the SE and NE, might be major limited - like if your state doesn’t have that major.
What I would say is get that budget and we’ll likely find you schools of various sizes and environments to fit. Even LACs potentially.
