This was back in the pre-internet days of ads in the phone book and local papers. Yes, I'm that old. LOL.
I called a few agencies with ads in the Chicago Reader; after a couple I found a woman-owned-and-run agency I liked and had my first date a few hours later. Easy-peasy.
But..... at the end of 2014 & beginning of 2015 I was trying to make a comeback after a long hiatus. Weeks went by with no real interest. Even my former regulars were waiting for someone else to take a chance & write a new review for me.
In a last-ditch effort, I ran a low-low special on my local Ad Board (note that it CANNOT be worded as a "review special" or in exchange for reviews or anything like that!) which finally snared me a few dates. Almost all of them wrote reviews for me and I was back in business.
I'm not saying you should do this, or that it's necessary or anything like that.... .this is simply what worked for ME in my situation. You do you. Write a big, splashy ad with lots of photos and show off how excited and enthusiastic you are to be joining the provider ranks! Showcase your personality and energy.
And of course, posting as many photos as you have in replies to your own ad may also help.
Just think about your image, branding, and how you want to be perceived. Then go with that!
Good Luck!!!!
