first thing I would do is put stuff to one side that needs specialists to do plating etc
then box the other stuff into modules so you can concentrate on one thing at a time.
try fowlers parts online as the have a parts fiche you can look at and get part numbers (sometimes its cheaper on ebay) and also see if the part fits other bikes which braodens your search
I prefer powder coating and they also sandblast it as part of the charge. my local one charged me £65 for the gilera frame and swing arm, depends where you live. make sure you view their work as I've had stuff done whichj was terrible and was so thick in places, parts didn't fit
