I deal with accredited investors on a daily basis. 90% of them contact me by phone/email and will not fill out an online form. I think that a good way to go about this is to target very high-paying industries and buy lists of those industries, then send out letters to those individuals. For example: buy a list of all plastic surgeons in the US. then send out physical mail or pay someone to call them each and tell them about your program. Driving AIs to you won't happen, you need to reach out to them.
