Geoprocessing Service: Will the following work?

I need to publish my python script as a geoprocessing service, which I've never done before. The geoprocessing service needs to take as input the SSRS Url, extract the SGID value, generate a jpeg of the map linked to the SGID (Cadastre ID) and return the output jpeg path as an url that the SSRS can use to access the jpeg to insert it into the report template.

We currently have the following CMV viewer (V&V Mapper) that we are using. Our SQL Dev has written a SQL SSRS  report that is triggered when the following link (Tablemap) below is selected.

TableMap: MoreInfo


I've attached my python script below that as an input argument accepts the SSRS Url and extracts the SGID value using Python Urlparse module (i.e. I'm still using Python 2.7.8 and ArcGIS 10.3.1).

            for row in scur1:
                elm_title.text = row[1]
                SGID = row[0]
                def_query1 = "{0} = {1}".format("SGID", SGID)
                lyrs[0].definitionQuery = def_query1
                lyrs[1].definitionQuery = def_query1
                df.extent = row[2].extent
                df.scale = int(math.ceil(df.scale/5000)*5000)
                output_jpeg = "{0}\\{1}.jpg".format(output_folder, SGID)
                arcpy.AddMessage("Exporting SGID {0} jpeg".format(SGID))
                arcpy.mapping.ExportToJPEG(mxd, output_jpeg, resolution=150)
                lyrs[0].definitionQuery = ""
                lyrs[1].definitionQuery = ""
    except arcpy.ExecuteError:
    return output_jpeg

output_jpeg = vandv_ddp_jpegs(input_mxd, sgid, output_folder)

Any suggestions to achieve the following will be appreciated as I've never done the following before. Will the following accept the incoming url from the SSRS request and return the url path to the output jpeg.
