As I’m sure you already realize, your GPA is great! Although it’s good that you’ve done a research project and presented it, most of the schools on your list are extremely competitive (except for maybe CU Denver and UConn) and, as McMurphy pointed out, many of the applicants at those schools will have presentations at regional and/or national conferences (as well as possibly having lab experience at an R1 university) and this will probably put you at a big disadvantage. If you can’t get a paid job in research, have you thought about being a volunteer RA? Admissions committees will look favorably on this, and I know people who volunteered at CU Boulder, UCCS, and Metro State to get research experience before grad school. This would give you an opportunity to get on poster presentations at bigger conferences and/or be published.
