Wood sign store website

I like to have a website similar to https://store.acustomcut.com/customize/wood-name-sign where customers can enter their name, see the font styles, select a color of their sign, and based on the size and thickness it will show the price in the end, and also check out as well. I need to manage the fonts, colors, sizes, and prices after the project are done. Don't worry about the look of the website but it should function like the link I've attached.
