Are you sure you want 100% plates?
I can help you if that is really what you want. However, I strongly suggest you consider 80% plates and finish on your parts kit. Plates completed to 100% would be true to blueprint and easily apply to all new parts. I would be guessing but I bet you plan on building on surplus USGI or Israeli parts kits.
While the probability is high that a new plate built to blueprint will work fine, it would be a real bear to correct the top and bottom plates rivet holes if your older, used and demilled kit were out of spec.
With the plates I offer at 80%, all you have to do is drill out the round holes. All the remaining mill work is completed. The drilling and chamfer might take about 1 to 1 1/2 hours depending on your skill level. The fit would be true to your kits and the result would be guaranteed pleasing.
A plate that comes with all the holes drilled and chamfered will cost you significantly more.
I, as the builder, would charge you my shop rate $100.00 per hour to complete the plate (Read that as about $65 since I am already fixtured to do the work). FET (Federal Excise Tax) doesn't apply because you only want the receiver plate. an FFL dealer would be needed to accept the plates on delivery and then to transfer them to you. If you are an FFL holder that is a mute point. If you are not an FFL holder this fee may range from nothing to as much as $50.00 per plate brought in. Be sure to ask your dealer about the fees and have the deal written down prior to having the plates shipped. I won't say more than cover your a$$ with a contract to have the FFL holder receive the plates on your behalf.
I am happy to sell you whatever product you want (legally). Let me know if I can help.
