I'm interested to know the answer to this as well, but I dont think the corporate world see this in the same light as we do.
They will probably not be interested in the development platform, only the final product.
What the will be interested in, will be how many platforms you can cover (Web, Android, iOS, BB, WP7) and they will be happy to get as much coverage as possible.
The pricing also depends on how complex the app is...
Let me put a random figure I think an android app should cost a corporate company...maybe 1000 GBP = 1500 USD?
