There are a lot of free (and paid, depending on what you need) templates websites around. Here's one site that offers bootstrap front-end templates: https://startbootstrap.com/template-categories/all/ .  I don't know of any coin in that space, but I don't know every coin in the market (there are thousands of them!) so I think you should do your own research about that, I'm sorry. If you need anything else, feel free to ask!
