Well, since we're not talking about a firearm manufactured and NFA registered prior to the Firearm Owners Protection Act of 1986, you'd be considered a manufacturer.
The first step is to obtain the appropriate class of Federal Firearms Licence - in this case, you would need either a Type 7 or Type 10 FFL. Then, in addition to that FFL, you would need to obtain a Class II Special Occupational Tax Stamp. And that's all the information which will be given here. Such a conversion without licencing to do such constitutes an illegal act, and such how-to guides will not be provided here. It's also an easy way to net yourself ten years in prison.

It is a semi-auto pistol. Fires one shot per pull of the trigger. It is not a machinegun.
A single shot pistol, a Derringer and even a revolver are technically NOT considered semiautomatic. To be semiautomatic, the weapon would need to use the energy from a previous round to cycle the action. Revolvers use the muscle energy of the shooter's finger to revolved the chamber.
