Create Webservice that gets random product

Hey I am trying to create a web service that flash can load. The web service will create an array string with a random products info. I have tried different things and I cannot get the .asmx file to connect with NOPCommerce classes inorder to make the query. Anyone have any suggestions as to how to create a web service and possibly have some examples?

I did by this way.

crawl a target b2c website and analyse source of product page.

Unfortunately that is a little more complicated or should I say more inconvenient than I would like.
