Generally if you publicly post an e-mail address you are going to get spam as web crawlers find your e-mail.
I’ve been using Bluehost since they were cheap ($3/mo) when I signed up and had a solid back end system. As far as hosting goes, pure hosting services tend to be the cheapest - you don’t need to register your domain through them you can register through godaddy and then have it transferred wherever - it’s not too complex and usually can all be done once at setup if you need - but you still need something to build a site. If you just buy an HTML template and update it to suit your need, that is cheaper than using an online builder solution.
Squarespace probably has one of the better template sites but you’ll pay $8-16 a month for it. I tried using Weebly once in the past also.
