Equity should always be vested. But I am not even sure if you should give them any equity until you know for sure that they are worth it. Even if he lands you 1 or 2 deals, how do you determine the equity (even if vested) just based on that ? I am just a stranger on the internet so take my advice with a grain of salt. Based on what you said so far, it seems like you don't know this person well and you don't know anything about their track record. That is a huge red flag for me to even discuss equity. Too early. If you are bootstrapped and money is tight, you could perhaps give him a commission on the first few sales (a fixed percentage of the sale per client etc) instead of equity. If he is really interested and worth it, he will agree. If not, then you are taking a big risk by agreeing on equity upfront without knowing anything about him and his ability to sell.
