This is Adrian from Models First
One of our models has informed me that there is this thread and so let me answer this officially. Models First is a model agency and we have been trading since 1999 and have placed hundreds, if not thousands, of people in highly paid modelling jobs and launched many careers. No model agency, including ours, would ask a model to pay a penny towards their work. We have not and would not ask any model to pay us. It is our job to get models work and we receive our income from the producers who book them. We do indeed receive hundreds of applications per week from potential models and I'm afraid only a small percentage are successful and invited to go on our books.
As there are so many people who want to get into the industry but are not suited, I hear stories regularly from people who have been asked by companies posing as agents to pay money towards admin fees, portfolios and the like. My advice would be to never part with any money. Agents should be getting you money, not the other way around. Sadly scams reflect badly on the legitimate industry which is why there have been misinformed answers to your question.
