Producer app is very coplex to port. So insted we are working on an enterprise cloud solution for the industy. check out edictive.com

Changing Currency: Absolutely. The app is currency agnostic. You can set input keyboard and currency via you device config screen. So to recap this is iPad/iPhone setting.

Budget: Budget is broken down above and below the line, actual, and budgeted amounts per item as well as unit cost and unit. You are able to add unlimited budget items with your own comments data and comments. All this is exportable to a PDF. (v2.2+)

For a more enterprise solution there is a more complex and thus priced solution: edictive.com

Great ideas there, schedule is on the functionality roadmap for producer together with export of schedule to PDF. The automated call sheets is something we are implementing in the upcoming Edictive.com so this may be an interesting one to look at also. 

Sounds like a great idea. This is something we are implementing in the upcoming Edictive.com
