Clean up and improve Wordpress website, and add Shopify storefront with integration to Printful dropshipping

We have a nonprofit, Spread Positivity, and the website needs to be cleaned up and maybe improved in the process. You can see the current draft of the new site at [login to view URL] The basic sections of the current version are nearly complete, but have broken links, and a few simple pages that need to be created. The main addition will be a new page for selling T-shirts. That page on the website can take people to the Shopify storefront (which needs to completed), and that Shopify storefront will list T-shirts from dropshipping service [login to view URL] . So, the work required here is basically: 1) Complete and improve new version of [login to view URL] - See more detail on changes at the end of this description. - New version should be easily editable in the future by a relatively inexperienced Wordpress user. 2) Design Shopify storefront - Can be basic. - Only starting with a few T-shirt models. - Products will be pulled from [login to view URL] dropshipping platform. - Ensure all works properly. 3) Setup Printful - Integrate it with Shopify. - Add products. - Ensure all works properly. 4) Explain to inexperienced user how to manage it going forward - Adding pages to website. - Changing copy on website. - Adding/changing products in Shopify store. - Adding/changing products in Printful.
