I can't actually help you with where to find a beveler, but, let me just say that every single one of my customers loves the fact that my soap "doesn't look like Dial" They've all told me that the "imperfections" are perfect!
When I don't get the bars exactly the same size, or same shape (don't have more than 2 glasses of wine when cutting soap) they love it!!!
Folks know what handmade stuff looks like, and well, it looks handmade. My customers don't want every single pink to be the same shade or every single bar to be the exact dimension of the last one. It's actually a selling point!
So, go with it. Each bar is different, embrace that!

PS-$80 for a beveler is way too much in my opinion
