There is another option which you might call a.(1). That is to lace the wheels yourself, and then take the laced wheels to a LBS for final tension and truing.

I have a set of Campagnolo NR hubs laced with DT spokes to a pair of Mavic GP4 rims. I laced the wheels with just enough tension to hold the hubs securely, then took to a LBS for dishing, tensioning, and truing. That was about 1985 and I"m still using the wheels.

But honestly, I would buy the equipment and build the wheels myself.
