How many providers did you contact, and why it didn't work?
Timing, distance, price?
If you reached out to them by instant messaging is very easy for them to get back to you a few days later just by scrolling down their previous messages. If you did it by text some texting apps remind you of a former conversation and suggest you reach out again using artificial intelligence. It works similar to predictive text. For instance I just got a message on my texting app telling me it's time to continue certain conversation I had a week ago and suggesting what to say. Spooky, isn't?
I have a feeling you are trying to create a self-fulfilling profecy of times being tough so clients can get a cheaper rate. Summers are usually tougher in big cities because people with money travel abroad.
