Werd, Lou.
In a world where fuck knows how many whores have their own websites and email addresses based on those domains, a producer should be able to cough up the what, 20 bucks or so a domain email would cost?
If you want to be taken seriously as a producer, get decent business cards, a fixed line tel. no. or answering service (using human beings) and a domain-based email.
You look permanent, serious and organized. Not like a fly-by-night-operating-out-of-his-mom's-basement kinda guy. Ownership of a 3 CCD MiniDV cam just does not guarantee a VIP pass to the party anymore.
You'll get less hassle from agents, less hassle from suitcase pimps and a better reception from the whore if she believes that the facade you've put up is genuine.
Please note that this system can also be used to scam widows out of large inheritances.
