My partner and I got engaged last fall, and I knew with the pandemic that photographers/videographers were getting booked up fast, so I wanted to make sure I booked mine early. I was between 2 photographers, and I ended up going with one that I know through some friends. I haven’t signed a contract, I emailed her and said we wanted to work with her. We set up a date to take engagement photos. The week before we were going to take the photos, she emails me and suggests we reschedule due to things outside of our control, totally fine. I suggested another weekend, she said she might have plans so she would have to let me know. I said no problem, let me know. It gets to a few days before that weekend, and I hadn’t heard from her. I emailed her and suggested a handful of other dates that we could do (since that weekend obviously wasn’t going to work). She said she only had one weekend available, and then she was booked until October. I was a little annoyed by this, but agreed to the date that she sent. That was 10 days ago and I have yet to hear from her. Is this a red flag? Since I haven’t signed a contract, am I even allowed to switch photographers? Is that a faux pas?
