I have three questions related to this:
1) What do you think about using Paypal to process payments? I chose them largely because of branding and because you don't need to have a credit card to buy. This is important because my potential clients are definitely not accustomed to paying for things online.
3) Can you suggest an alternative to Paypal? I'm currently considering Google Checkout. Do you have any other suggestions? It would be really great if I could offer a non-credit-card option of payment.
Much thanks for your feedback.
