I’m in middle of learning safrus from a very good rebbe R’ Yisroel Landsman. He will come to you makom. But he just teaches the skills i.e. ksav, sirtut, making a kulmus. The halacha ayou have to learn on your own. He can be reached at 718-404-4249 or ask the mods for my email
To get a ksav kabala you have to learn 1)Mishnas Sofrim (found in Mishna Berura Chelek Alef) 2) shulchan Aruch siman lamed bais and lamed vav w/ Biur Halacha 3)keses Hasofer- Found either in a sefer called Likut sifrei stam (aprox. $24 in ny) or with a perush Called Mishnas Hasofer Aprox $36 in ny
