Transfer Portal Help

hello, currently Im a rising sophomore running d3 track and field and a sorta academic school. I improved a lot freshman year going 3:49 in the 1500 and 1:52 in the 800. I have good grades and am wondering if I have a shot at transferring D1 potentially to an Ivy League school. If so how can I start reaching out to coaches.

sorry if any of these are dumbass questions I don’t know anything about the transfer portal and everything I found on google has been confusing.
