I am not completely sure where you take the "fake" part from, but if whatever people have asked you doesn't make sense to you, then not many would be able to help you. All people have asked you are reasonable questions ANY interested hosting company would ask to make a decision to sponsor you.
I will give you an example. You say you have a big company and all your clients will be referred.. no, not the word - "required" to host only with you. Personally, I don't see how you can make someone to host with a company unless using some sort of threatening. Fine, let's skip the issue. Suppose they do come to a hosting company that sponsors you - how many clients can a hosting company get in exchange? If you are a big company, you would know how many clients you guys server on average every month.
Those are the questions that you will be asked. Instead of answering them, you just state what YOU need, and completely forget about those who you asking help from.
Good luck.
