You can create the service directly in the web project but better to put it in a seperate project so that it can be reused elsewhere if neccessary. If you do the latter you will just need to create a *.svc file on the web site to identify the service. Just the one line:

< %@ ServiceHost Language="C#" Service="My.ServiceLibrary.Service" % >

where Service is the class of the service in the referenced project...

>And, would you create a service specific to the data, or a more generalized service that can access any data?

My 2c : Keep it specific.
