Where can I get these zanpakuto (Cosplay)?

My fiancee and I are getting ready for our cosplay wedding and have decided to go as Ichigo and Rukia (Bleach). We know where we are getting the outfits, but we need the zanpakuto as well. Where is a reliable place to get Sode no Shirayuki and Tensa Zangetsu? Price is a big thing as well (We've got other expenses to cover for our wedding after all not to mention bills and other needs). They must both be made of wood and not sharp (Metrocon has restrictions on weapons, but if they are made of wood and not sharp, they will be fine).
