Boutique ib internship told to reach out week before summer

Hi,

So I'm from the southern hemisphere where our summer is December-February. I've been cold-emailing pretty much all the boutique ibs in my city and have finally had one reach back to me. After a string of emails, he told me that he may have a transaction for me to work on and that he is currently waiting on the client to sign his mandate noting that I should email him back again towards the end of November (week before summer starts).

Is this something I should be concerned with? don't know if I should continue cold emailing other firms and their stance of being "put on hold" so to speak
