if you need hosting and the builder - weebly.com is a pretty good choice - there are drawbacks of course to any sitebuilder, and limited HTML knowledge.
But in my expereince if you are not looking for a CMS, just a "drag and drop" builder - weebly is 100000 times better than wix - as you found out wix is HORRIBLE for SEO.
If you are looking for a little more customization - just find a host that offers a sitebuilder - like Fatcow - they offer weebly pro for an additional price AND you have all the FTP abilities to make advanced HTML changes and additions after using weebly to publish the core components.
Learning HTML and becoming very proficient in it, and its counterparts (php asp ect..) is crucial to SEO though...
Hope this helps
