I think the website is pretty snazzy and is illustrative. Is this a WordPress template? If so, would you recommend any managed WordPress hosting site - WpEngine? Our performance on Siteground with Cloudflare has been less than stellar.
I've used WPEngine and haven't experienced much issue myself. Their support has been good and pretty helpful with managing tricky mysql situations.
I have used dreamhost for other sites but the performance is so-so... Not bad but not great either...
another option but more hands on is a digital ocean droplet - it's also a little more pricey.
