This is currently the website I use to host my own portfolio, and they have really nice, attractive layouts to chose from! They offer a variety of levels for pricing and I was able to attract a few clients with it.
A website affiliated with Adobe, you can create a free portfolio in minutes if you already have Adobe Creative Cloud. Even if you don't have that subscription, I do believe there's still a free version. Another thing to consider is that there's a plug in on LinkedIn that makes it extremely easy to link your projects from Behance to your LinkedIn portfolio.
Haven't used this as a resource yet, but they have some really attractive layouts and templates!
Really Nice Layouts offered here as well!
A ton of professional looking layouts!
