Smokey,.... first let me welcome you to our TMA site.
As for naming names of a good gun builder, please be aware there are quite a few who would and could build you a French Fusil, I won't mention names because some else will surely feel slighted if their name isn't mentioned (and I want to avoid that).
I'd suggest you visit the American LongRifles Forum, and post your questions there, just state what you're wanting built along with how much money you're willing to pay, and you should get numerous PM's (private messages). Just be careful if you get a message from someone with the initials JB, as his builds can often be disappointing (although his prices are very attractive).
