BS MD Counselor - Recommendations

I grew up outside of USA and never had a chance to attend a school in US; so my college admission experience is very limited. My son is going to graduate next year/2018. He would like to pursue BS MD program. Based on his credentials and what teachers and others are telling me, I believe he has a good chance of getting in if everything works out well.

One of the things we have been discussing is about BS MD counselors. I am sure there will be different opinions here also regarding its needed or not. Its not that I am filthy rich or anything but I don’t want a situation where he misses this opportunity due to lack of support on this aspect. . Worst case is that it will be close to $5k plus or minus down the drain in case he doesn’t make it.
Anyone has experience with BS MD counselors? What package or options do you recommend? Can you all recommend some experienced counselors who specialize in BS/MD? I have searched locally and couldn’t find anyone.

Thanks in advance
