Geoprocessing with ArcGIS Server 10.1

I'm new to Geoprocessing, but would like to determine if I have a model created in ArcGIS Desktop Model Builder, can I convert that model to a Python Script for publishing to ArcGIS Server?

I would like to convert it to Python because I want to add a couple of things that don't seem to be possible in Model Builder, such as write some output to a CSV file or even a text file. The Model Builder only seems to support GeoDatabases for output. Is there a way to output data to a CSV file once published to ArcGIS Server?

Thanks,
Charlie
