I need help with an existing WordPress website for TMS

The domain name is: www.thementalswitch.com.au

I already have the WordPress theme and need the following features:
- Customization & plugins
- Calendar integration
- Email marketing
- Social media integration
- Tracking & reporting
- Elementor
- SEO

I'm looking to add email, marketing, reels to the website for references, I book in calendar for clients, and more activity under the specific tabs where we offer services
