Well, that was unfortunate. Don't know who you were talking to, don't want to know. Something you said or did, probably unintentional, set him off. He could have simply said he wasn't interested in your business and sent you away.
Talked to "professionals" for 7 hours and determined that you should use slide-a-links and QA-1s? He probably did you a favor, although I would probably be hesitant to pay him a consultation fee of $700 for that bit of wisdom. Get a receipt.
