Do Garry's Mod Server hosts also include CS:Source downloaded through srcds?

The issue I’m having is that I can’t seem to get my srcds.exe work on my own computer when I download CS:source after I’ve downloaded Garry’s mod (ID: 4020, using the steam server downloader program). So I’ve given up on a home server and have decided to purchase a small 10 slot server to try and play a gamemode that requires CS:source content to be serverside, which I cannot do on my own.

So I’m wondering if anyone knows of any specific server hosts that have CS:source content on their Garry’s Mod server orders? Such as NFO, Xenon, etc.

They all do, usually they will have a shared mount folder for css content etc.
