I have about $25,000.00 tied up in my leather shop ,an see thing every day I want to get, it has taken me over 20 years to put my shop together, so hand cutting is all right but you will need a good clicker to make money out of it , I can not tell you, how much I have tied up, JUST, in my hand tools.
You would be better off finding some one getting out of the leather bus"""and you MUST have a good sewing machine ,like a Artisan 3000< I have one an it has never fail me , The tippman BOSS ,you will have a hard time keeping it in time, an lot of gun hostlers you will need both hand ,when sewing them, I just want you to know a leather shop take time putting it together , Just start out slow an build to it . good luck.
