well you came to the right place. There's plenty of scratch build threads, for the stuff you wanna make entirely by yourself, there is our gallery with extensive pics of Boba and Jango form the film clips and exhibitions.
If you wanna buy stuff, the cargo hold is where you wanna be! You can buy armor kits (unclean, straight from the mold) and clothing all the way to having someone make the whole thing for you (though that is much more expensive). I would recommend researching various vendors first (ie; Redkraytdragon, Dark-Side, Mojo-Fett, Fettpride, Bobamaker, Asok, the list goes on...). Some vendors are better at specific parts so it pays to look the merchandise over to know what stuff you like most!
Welcome to TDH by the way! Hope you find what you're looking for!
