College Admissions Counselor Recommendations

What are some recommendations for college admissions counselors that works with students wanting to go to Ivy Leagues or other T20s? I feel like I’m in a pretty bad situation with my grades and really nervous about my senior year, which is next year for me (class of 2025). Unfortunately, the person I was going to go for, Tineo College Prep is full for 2024-2025. So what are some counselors that you guys recommend?
