Setting up streamlined ordering with data-driven graphics?

Setting up streamlined ordering with data-driven graphics?

So this is what I'm working on. I work in a print shop that produces
sports jerseys. Once the template is set up, producing the individual
names/numbers on the jerseys is easy. In Adobe Illustrator, I can use
variables and batch processing to automatically process an excel sheet of
names.
However, I would like to streamline this process further. What I'm trying
to create is a webform that clients can use to create the entire order.
Collect contact information, get specifics on the jerseys, and then enter
in each player name, size, and number. From there, I want the data to be
exported to an XML format in a schema that works with what illustrator
wants.
I made a form in Orbeon just to test it out:
http://demo.orbeon.com/orbeon/fr/orbeon/builder/edit/fec0bfc55dbe6042d88b7467f2c600dfb22cc4b2
Right now, I'm really not digging the interface. It just isn't user
friendly. Even then, I wouldn't know how to set up the XML schema in order
to be friendly with Illustrator.
Should I ditch Orbeon and go with something different, or is there an
easier way to get Orbeon working?
