Need an engravers app for my product page

Hi Everyone! I have a business that cuts metal letters. I want my customers to order letters and preview them in the font they choose. Also the app would charge by letter. Have been looking for something like this for a few days now. No luck. Can anyone help? This is an example of the product page I am trying to do https://www.craftcuts.com/foam-letters.html

Hi, fancy feature and idea. I’m sure your customers would love to see what they will get.

I found this app called Custom Product Builder from the app store, which seems like meeting your need.

Not hurt trying it out.
