2. Write a short, clear bio.
Things to include:
3. Keep your gallery focused and your quality high.
I'm sure your kids / puppy / new shoes are adorable, but if the photo is not in line with the work you are aiming for, don't post it. Everyone I know has a separate "personal" account where they post blurry club shots, their cooking exploits, and selfies for family and friends.
With that, your gallery should be curated to be somewhat niche. Someone should be able to get a feel for the kind of photos you take by looking at your gallery. Of course, most photographers are comfortable with a variety of subjects. But I'm telling you: the focused gallery is going to get the job. A restaurant group is going to be looking for someone who takes great food shots and flat lays; an apparel brand is going to be looking for portraiture with a look and feel that matches their brand -- you get the idea.
4. Sign up with any agency you can.
There are load of agencies out there who are looking for influencers -- just Google it. Sadly, a lot of them are still pretty outdated in their thinking. They look for a large following without much regard to quality of engagement. So this method works the best if you already have about 10K or more followers. Still, it's worth signing up for as many as you can. Maybe for every 10 agencies I make a connection with, I'll get one job.
Some people call it being thirsty, I call it hustling. A lot of my work comes from interpersonal relationships and word of mouth recommendations. Need more info on exactly how to network? Check out this blog, or this one.
