Thanks for your comment! I highly recommend searching for a luthier if you want to build your guitar from scratch. He or she will guide you the whole process and you can be sure to receive an instrument which meets your expectations. I will use Duesenberg single coils pickups (http://www.goeldo.de/pickups/single-coil-pickups-u.-rahmen/2889/duesenberg-ds-alnico-blade-pickup). If you have enough money and can wait a little bit I guess a pickup builder from the following list will be a great choice!
