I'd bet if you go to Home Depot or Lowes and explain your project to someone, they can point you in the right direction for tools and materials. One thing I would say to keep in mind is the type of wire or attachment fastener you use because galvanized metal has to be treated with a vinegar water solution or the residue of the metal treatment can come off on suggie hands, and if food touches it for any amount of time the metal can leach into the food. I'm sure they have J-clips and J-clip pliers, which is what a lot of commercial cages are fastened together with. Beats the heck out of baling wire, lol. :P
