Custom co-ordinates services

I have a map service created using prj file. and the service SP looks like a string.

Spatial Reference: PROJCS["NAD_1983_StatePlane_Georgia_West_FIPS_1002_Feet",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",2296583.333333333],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",-84.16666666666667],PARAMETER["Scale_Factor",0.9999],PARAMETER["Latitude_Of_Origin",30.0],UNIT["Foot_US",0.3048006096012192]],VERTCS["NAVD_1988",VDATUM["North_American_Vertical_Datum_1988"],PARAMETER["Vertical_Shift",0.0],PARAMETER["Direction",1.0],UNIT["Foot_US",0.3048006096012192]]

Can I use proj4js conversion using this?

I don't know if proj4js supports EPSG well-known IDs, but PROJ4 does. The WKID for this Georgia West zone is 2240.

You can get a PROJ4 string here.

I have created map service using the prj file. I am using javascript API to use this service and I have aerial service which is in
stateplane.

However the map service(created using prj file) is not loaded on the Map.(I have working proxy url).

Thanks in advance.
