Greetings,
We are a software development company based in Ireland, our focus is primarily in Java. We estimate that with your requirements, this project can be completed in about one month. A Java desktop application can be created to retrieve the needed Quickbooks data and display/store it within a format you wish. If you have any further questions please don't hesitate to ask!
Sincerely,
Owen McMonagle.
