where to find larger gauge septum retainers?

hai! 8g septum-haver here. I live in a cold place and dislike the condensation that drips off my horseshoe during the colder months, so I'm looking for a staple retainer but can't find anything!! help! I'm fine with either titanium (preferred), stainless steel, or glass. must be a store that can ship to canada! thanks friends :)
