Hutch,
The finish kit contains the doors and windows (unless you order the Cee Bailey transparencies). Fitting the cabin cover and doors can occur fairly quickly after getting the QB fuselage.
I would suggest you contact Allen for more information assuming you are planning to continue to work with Synergy Air South.
We just did my doors side by side along with another builder's RV-10. It took two full weeks to do that, along with installing the Plane Around latch system.
Lead times on finish kits (and just about all kits/engines/panels) are a bit longer than you would expect.
