I'd be happy to hear about a traditional hosting company that allows clients to install lets Encrypt certs if you can name any...

Most of my clients don't have budgets big enough for cloud hosting.

DreamHost allows it.

Not only do they just allow you to import any certificate you want, but they literally have a button on the panel to get one from Let's Encrypt for free.
