25 years ago, there were only 2 agencies in Indianapolis. Today....there are several who pretend to be "agencies." In reality, however, there are still only 2 legitimate agencies in Indianapolis.
Avoid the scams that tell you they are going to make you a model in Los Angeles, New York, etc. It's just a scam to get you to pay them a lot of money. Same with the scam "agencies" who post, almost every day, that they have someone working "on set" with some local company whose name was chosen for the scam because they know they won't get caught using it. And then there's the national scams with an office in Indy. Only a fool would get caught in that scam. Don't be a fool.
Just as it was 25 years ago, there are 2 legitimate agencies in Indianapolis. Stick with what's real and avoid the clever scams that just want your money (and a lot of it.)
