Hi Dwayne, I'm not sure how complex your currency formatting needs are. But I think you should be able to do a lot of this yourself in Elm—especially if all you're looking for is commas and dollar signs.
I threw together an Ellie app to get you started. https://ellie-app.com/34vgDLqvmd6a1/1 Would something like that help you?
