WordPress Customization Help for a WooCommerce Site

General information for the website: Sells Books and Courses for Spiritual Practitioners
Kind of development: Customization of existing website
Description of requirements/features: Most of the basic site structure and design is in place. The site is built using the SiteOrigin Vantage theme, SiteOrigin Page Builder, Pods, along with WooCommerce and the Sensei LMS plugin also by WooThemes. So familiarity with these tools would be a plus. The site also integrates with MailChimp with the MailChimp WD plugin.

I need various help customizing certain pages and page elements including:

- Adjustments to layout and CSS for the course and shop pages
- Configuring and styling sidebar widgets
- Styling the course landing pages
- Setting up and styling the contact page
- Help configuring user roles and access
- Linking course landing page with course purchase and registration
- General CSS and problem solving to complete various pages and features
- Help creating a great experience on all devices for the above customizations

I am comfortable with basic html and CSS, but I would like as much as possible for the front-end content to be easily editable through the admin.

Would prefer someone who is experienced writing clean code and doing back-end customizations "the right way", but also has a good eye for design.

Would prefer someone who is able to work with me in close to real-time during U.S. hours.
