First Paid Shoot Tomorrow! Advice?

[StellerCrys]

Hello everyone.
Ok, I've been waiting for this day for about a month now since the client first made the appointment.
I will be taking pictures of 3 ladies, sisters actually. We will do some at a local park, and then back to my home studio for some shots in front of a white background I have. (also have a few homemade lights, worklights with cloth diffuser panels in front)

I was hoping some of you might have some words of wisdom, advice on how to conduct myself concerning first interaction and payment discussion/collection.
Also any pointers for certain shots, and/or must have shots.

Thanks everyone!

Let your personallity shine through, use your ideas, but ask if there is anything that they want to do, and then tweek it to make it look good. As far a payment, don't be afraid to ask for it, and don't say your sorry to ask for it. They are paying you for your service, so be professional!

Too late for an answer now. Next time ask a week ahead? ;)
