is daniel browne agency a scam? they asked me to pay 500 pounds for a portfolio? do you know anything/or have heard about this agency?

DO NOT GIVE THEM ANY MONEY! THIS IS A SCAM. NO LEGIT AGENCY WILL EVER ASK YOU FOR MONEY UPFRONT, EVER, PERIOD, FULL STOP. I cannot stress this enough, no matter how bad you want to model or how good the deal seems, run a mile .

Ask away.
