That answers my main questions
Yeah of course
My last ad was:
"Hello I'm (name) I would like to build a photography portfolio.
I am no means an expert photographer, but I hope to start eventually. A model would greatly help.
They need more info -- what kind of portfolio? Portraits? Fashion? Pinup? Sexy?
Compensation $50 for one hour"
Wrong amount, in my opinion. I you're looking for clothed, normal things it's too high -- you look desperate. If you're looking for nude or porn it's too cheap.
You might actually do better offering "Time for Prints" (TFP) instead of money -- looks less desperate.
Then the models would reply with interest, I would reply back: "hello (their name) would you like to meet at (x) ? If that area is too inconvent we can meet elsewhere.
Thanks"
Again, they need more detail - -what kind of photos? Do they furnish wardrobe or makeup? How long? Do they get photos as well as cash? Don't try to close the deal too soon, allow for some discussion and back-and-forth.
And where can they see samples? You need samples, even if it's just a few beginner quality photos. If you're showing on social media do you have a separate photo site? Nobody wants to sort through your cat pics or photos of your lunch to get to the model photos.
And then ghost
No surprise. But it happens and you have to expect it -- even with a good pitch maybe one out of three will come back with a second response. Maybe of those one out of three will actually make an appointment and show up for photos. And that's with a effective campaign. So overall something like one out of ten actually make it to a photo session. To some extent it's a numbers game.
Polish your act and keep going.
As others point out, there may be better resources in your area. Hopefully you have a social media presence and following. In my own somewhat rural area there are perhaps half a dozen Facebook groups for photographers and models to make connections -- much productive than Craigslist. Most of my recent contacts have come through Instagram -- and most are friends/followers of people I had worked with who have posted my photos and said nice things about me. My impression, though, is that TicTok is really the place to be. I don't get it, but I need to figure it out if I'm going to keep going.
Get really nice photos with one person and treat them well. If they like you they'll say good things to their friends and you'll be up and going.
Good luck
