What Web Builder Software and Webhost best for professional looking website? Cost not really a big issue.

I think i prefer to use notepad++, sublime text to build sites. if you are looking for site builder portal then i think there are lot of available. I would recommend hostgator as a web host and if you are comfortable then look for there site builder portal they do provide templates.

I had Hostgator and their sitebuilder did not allow me to create drop down tree menu's.

If you could make "professionally looking sites" by pointing and clicking then Treehouse wouldn't exist.

Closest thing I've seen is jetstrap it allows you to create bootstrap code by drag-and-drop

It is better to learn how the website is structured. I always notice when people use templates or code they have copied that after a while when have issues with it, they don't know how to fix it. Notepadd++ is really good. If you can afford Dreamweaver that helps as well.

The webhost isn't going to matter much unless you expect astronomical traffic. I would recommend to NOT use Go Daddy for hosting. I use Host Gator, it works fine.

I don't know who to recommend for a "site builder". Normally that comes with the web host. It would be better to use a pre-made template from Theme Forest (if you really must). I would not use a "site builder" at all if your goal is to look professional.

If you can, hire someone to build the site for you (if you do not have time or adequate skill to build it yourself). You have a much better chance of getting a professional looking site than by rolling out a web host site builder. If you go that route, you stand a great chance of having the site builder links visible to everyone, and that will not look good.

You should use WordPress, it's an easy CMS software for building your site. If you are using HostGator, there will be an option inside your cPanel where you should be able to install WordPress with 1 click.

Your WordPress site will look plain at the start, but you can make it look professional by purchasing a premium theme like the Genesis Framework.

You can easily create the drop-down trees too, using the WordPress menu feature.

Thanks to all who responded. Very helpful,
