Thanks Martin, great reply! You need a meeting, not even a call suffices.
But listen, the clients I'm writing about are not heavy duty big advertising. Small fry -- but not consumer.
Could be publicity company who has been hired to shoot some corporate headshots or an local event. These are not dreams job, but could pay, $500 to $1500 for a few hours.. So easy rent money.
I can't turn them down flat.. many are actually legit; but I find it highly annoying some (probably young millenials who don't use phone much), so wont call or do a call, even though I've emailed to call to discuss it - which would take 6 minutes or so.
That said, of 6-7 that I've emailed rates to, I've never gotten the gig anyway. So even though I need the money, and is probably legit.. I'm thinking of composing a letter that I can't do business with them and keep me in mind for future gigs that are important enough to call; or maybe just not respond to their response which informs me they don't have time to call, but need a general quick quote...
