I am in a similar situation to you. I had a career first in investment management consulting, then asset management operations, and hedge fund operations. Having worked at small firms I have always had some role in "front office" type responsibilities (research, junior PM, and risk management) in addition to my operations duties. I am a CFA charterholder and have some experience prop trading now. I am also looking for a firm that will not require a training fee. Because I have just purchased a house I will not be able to contribute capital up front. However, I do have a strategy and a short track record.
Even if you have the hefty enrollment or training fees these firms charge, it is not a good idea to hand over so much money to join a prop firm. You are unlikely to see that money again even you make money for the firm. They have so many ways of keeping your money. Read the Prop Firm section of this board and you know how hard it is your get your money back. Even if the firm is solvent now, its condition can change very suddenly. The other consideration is that firms that charges a hefty upfront fee makes its revenue form new traders sign up, not from trading profits. In other words, they don't care if you lose all your money, they make money you win or lose. Instead of helping you succeed, they get rid of you when you lose half of the fees you paid them. Their goal is to get a constant supply of new traders willing to pay their upfront fees. They care very little for the success of the traders who are already with the firm. Find a firm that makes money only when you make money!
