Assuming Philadelphia, PA is USA this is not an option ofcourse.
Now, I don't know much about sites which accept US-players, but I assume traffic in games like RAZZ is probably pretty low.
Pokerstars is the only site for Razz. 1-3 tables on limit for cash and low buyin tours during a day. I also play HORSE and 8-Game tours. And daily tour 27$ for Razz and 82$ weekly.
