PDF Form Needs Dynamic Tables and Rows in Tables

I have a PDF contract for computer work. Customers select services, recurrence, etc. by machines and/or groups of machines. I hope Acrobats PDF forms allow users to add rows and tables of rows. I hope you'll see what I mean in the attached example document. You'll see there are two sets of two tables. I'd like to start with only one table for Workstation Group 1 and have a button to add a new workstation group, which would be called Workstation Group 2. The person could then add Group 3 if needed, etc. Then there would be only one row in that group and a person could press a plus ( + ) to add another workstation to that group. The MOB subscriptions section would work similarly. If this is at all unclear please let me now. I assume this is about an hour or so job for someone who knows more about Acrobat forms.
