Counselor to help with transfer from a private university

Can anyone recommend a college advisor who is very knowledgeable about transfer applications -- not from a community college into a UC like many of the posts here, but from a private university into any type school (public or private, U.S. or Canada) on the West Coast?  We could use advice on how to find the best transfer matches, advice on whether my child's transcript (good grades but not a lot of course variety -- freshman year concentrated in STEM classes) meets a given school's transfer requirements, info re transfers in the computer science major, advice about whether to attend sophomore year at the current school or to take a leave of absence while applying to transfer, and info re which schools do the best job of warmly incorporating their transfer students.

I see lots of encouraging recommendations here for college counselors generally, but am hoping to find someone with deep knowledge on these transfer questions.  (There is one answer from many years ago, but hoping for more current information.)

Thanks!
