I'd hope your not my competition before I go spewing advice
I'd recommend you join the
Center City Prop. Assos. it offers awesome networking events and other benefits.
You can stop by a lot of their events at a non-member rate to try them out too if you prefer.
My company is a new member and we're very happy with it so far.
If you do decide to visit an event you can drop me a line or say hi as I'm almost always at their events.
