How about: ask for more! For enterprise there is no difference between $10 and $200 - the person setting it up cost >$500 anyway. So why not make 20x more and maybe finance your development properly?
I think people are very reluctant to spend more than $3 in the iOS App Store. Speaking of which, setting up a separate Apple ID for a status board seems like a huge hassle. Whose credit card do you set it up with?
We are not talking about "people", but about "enterprise". Also, don't use iOS app store as advertising channel, just as your payment processor. Might be a bit unusual, but it pays to check.
I mean that opening the App Store puts the employee into the consumer mode of thinking. Sure, it helps if you can convince them to buy before hand so they are already expecting to pay $100 when they open the App Store.
With separate Apple ID I mean that you will have to register a new Apple ID for the iPad you will be hiding behind a TV screen. Somebody will need to manage that, and you have to worry about somebody stealing the iPad and spending thousands on smurf berries.
