If it is truly static, just use S3 (and optionally Cloudfront). If you need PHP, look at putting Cloufront in front of your existing shared hosting, or better, get a VPS and run Varnish in front of Apache with Cloudfront. You can set up rules in Cloudfront to point to different origins based on URL, so you could point at an S3 bucket for /about or /news pages, or the /images* folder, and to your PHP server for /contact or /blog. That way you have maximum uptime for all the static pages and content, and you only hit your server for stuff that absolutely needs to be dynamic.
