GO BIG OR GO HOME! 
Everyone wants to be big, but almost everyone forgets a key factor: The bigger you become, the bigger everything else comes with it.
Nah I think that you can get only a few miners and still remain profitable while using hosting, where they host many other clients with you, which makes it profitable for everyone
I didn't see a mining hosting company with which you can become profitable. They either charge you more than enough, or have limitations that eventually don't lead their clients to an actual profit. Not to mention the issue of clarity, transparency, etc, regarding such sites/ companies.
