Website Organization and Payment Streamlining

I need my Squarespace website organised so that reviews from students can be shown to potential new clients, work of students can be celebrated and online payments for my courses streamlined. I don't have online payment options at the moment but I would like to add payment options such as Credit/Debit Card, PayPal, and Bank Transfer.
As an online language school, I need to be discovered more easily on Google and AI searches.
I need a marketing manager to advise me on how to promote my work on social media, funneling, early bird promotions etc.

Key tasks include:
- SEO and GEO
- Organizing all website content for engagement, reviews, students' success celebration, clarity and ease of navigation.

- Streamlining and organising course subscriptions and lesson package renewals.

Ideal Skills:
