I am looking to set up an secure online store for a client who I am designing a website for.

I am looking at using a 3rd party to process the orders for my client. I am looking right now at www.dxshop.com.

I figured setting it up myself using SSL etc would be way to complicated. Is this correct ? Can anyone recommend any other 3rd party order/shop procesing websites?

How much do you think I would have to pay a programmer to do it for me ?

The store will hold approx 50 items.
Thanks
