As we are not using a shopping cart program, what is a good method to do so?

Shopping carts are all over the place. Paypal has one. 2CO has one. Most payment processors will give you one for free as a means of facilitating your ability to make them money.

How do you take payments? That's the place to start. Often good software is already at your fingertips.
