This is a good approach, but we need to add one more level of separation because I don't want to be the investor. I have created an email addresses to disguise as the potential investor, who will then introduce Finkelstein.
I have cc'ed XXXX XXXXwitz on this email, who may be interested in hearing more about your idea. XXXX is based in LA, and has done some small/medium angel rounds in the past, though he is pretty busy right now.
