Ultimately, this would depend on the hosting provider and the configuration of the server. Dedicated servers, in most cases, are going to be 100% customizable to fit the needs of your company, so there really is no way of saying how much it may cost you without having an idea of the specifications that you are looking for.
My suggestion would be to compile a list of requirements and specifications and work from there.
