Based on the options that you picked, here are the best website builders that we recommend for you to build your portfolio website:
Wix has a large selection of professional, portfolio focused templates to help you express your creativity through your website. With an intuitive drag & drop user interface, relevant & easy to use features (such as this Pro Gallery tool), a growing Apps Market, Wix is a solid choice for you to build your website.
Strong support including phone, email, forum, & a very comprehensive help library.
Squarespace gives you eye-catching, mobile responsive themes for you to choose from. They also give you extensive styling options, but not full code access to heavily customize your design. But their designs are beautiful.
Weebly is one of the easiest portfolio builders to use. Their tools are not as comprehensive as Squarespace or Wix, but they are easy to use. They provide phone, live chat & email support, & has a good library of support articles.
