Did you end up finding something? I'm sorry that it took so long to get back to this. I've had a lot on at home and only just reinstalled sims on my laptop. Anyway, here is my clone of the Professional Actor Trailer, made buyable in debug/misc. Place it in your packages folder.
I made it as a clone, so I hope it doesn't interfere with the original one. It works just fine in game to buy it and use it, but I'm not sure if it will interfere with it being a career reward (you might end up with 2, none, or game crash as an unintended outcome). If this happens to anyone using it, let me know and I will try a default replacement and see if that is better.
