Amends to Wix site and new funcitonality

Description

I need various changes made to my Wix site, to add new elements and improve functionality. High attention to detail required:
- small amends to the overall appearance of the site since recent changes were made - connecting the correct email address for subscribers- adding downloadable leaflets and resources to the Resources section (I have about 8 that need to go in three categories, I will need to add more over time) and requiring users to subscribe in order to access them- adding a new blog- adding a new section to the 'About' page to introduce my advisory group
Following that I will need help setting up Wix bookings and payments- setting up bookings options for classes and webinars- adding banners on the homepage to promote the classes and webinars
