At the end of the day, if you don't personally have the facilities, yours is a supervisory role to a large degree. ie. finding painters, platers, wheel builders polishers and parts suppliers etc.
Once you have tracked down the resources and designed your bike, set to, ordering the parts you want, and stripping the bike. You'll need a decent socket set, a disc cutter and some flap wheels. Seems daunting at first, but take a bravery pill and get stuck in, cutting off all the old lugs and brackets you don't need, and smoothing the cut areas down with the flap wheels.
Remeber to have any new mountings welded on before you take the frame to the powder coaters, as forgetting something is a pain. Prepare items for plating well, as in my experience, the prep has a bearing on the end result. Find your local automotive style hardware store, and replace all the small fasteners for stainless allens and button heads. This wont cost bundles, and the attention to detail is worth the effort.
Work to your plan, know what you are doing, and grin, as your freshly painted, polished and plated bits come back and your new bike gradually grows as you reassemble it.
