Hours of operation: I am available to respond to communications between 9 AM and 6 PM EST Monday-Friday and between 11 AM and 5 PM on the weekends. Although those are the hours I am guaranteed to be available to correspond about projects, those are not the only hours I work.
Payment terms: I use SafePay almost exclusively, though I will use Guru Invoicing in certain circumstances.
As for payment methods, I prefer PayPal or credit cards (Guru accepts MasterCard, Visa, and American Express), but I also accept checks, money orders, e-checks, cash account funds, and wire transfers.
Preferred communication style: E-mail.
