In fact, with globalization, this is fast becoming the most common way to do business. My latest clients didn't meet me at all throughout their website creation -- except by some DVDs sent by mail, the rest was all achieved through online communications. I live in Connecticut, but maintenance for my clients from Florida goes with no stress: unless there's reason to meet in person, it's exactly the same thing whether the client is here or there.

Payment is also not an issue: I accept payment with credit cards through PayPal. An e-mail with a link to pay through PayPal's web site provides a simple, safe and fast way to make a payment.
