If you're thinking about hosting yourself it doesn't make any sense. If you think about collocation then it's better but in your calculations include the fact that hardware breaks and with dedicated servers you get it fixed for free, when you buy the server yourself you have to buy anything that breaks and replace it. Almost always it means more of your time spent in dealing with it, more time of your users with lower quality/no service and it adds to the cost. Of course it's an option but you have to keep those things in mind. And before you do it I would search for some other provider of those dedicated solutions (or vps) before making that step

Thanks for the answer, yes we are thinking in Collocation, we offer different kind of services, will start moving the lightest service first, just to see if we can handle the situation and learn from our own experience.
