Cookie House

I have a website in place for a new business that has been established.? It is a bakery with a small restaurant.? My IT guy had personal problems and has disappeared.? The website is nearly complete, and I have a paypal account.? I need help creating a shopping cart, buttons, and checkout availability.? Probably not a lot of work involved, especially if you can just tell me what to do.? Or, if you have the time, you can create all the buttons for me.
