This right here will prove true -- stable is the keyword.
While someone may come around and offer you this extravagant package, they are most likely doing the same for others as well. I don't think anyone willing to offer these resources for a mere link back will do so for free.
And as a note for starting out, I'd NEVER subject clients (free or paid) to a free hosting service of someone else. If that host decides on Monday their going to shut down and do so, everything you've worked for is lost and you really have no control whatsoever.
By the way, I don't know of a VPS/dedicated under 100 dollars that has a 500GB hard drive in there -- 500 GB is an insane figure to expect from a free host.
