NextJS & Material UI Mobile Website

I have created a mobile website with nextjs and material ui. I need someone to come on board and make it look a lot better.

Tasks to be executed are:
- Add some nice fonts
- Add some additional elements to fill the space a bit
- Make it a little more mobile friendly
- Make Calendar fit a bit better in the page
- Allow dates on the calendar to be marked to simulate when a date is booked.
- When you click on a marked date it redirects to the booking details page.
- Make the upcoming booking cards look better.
- Improve the booking details page.

Everything is already built, it just needs to look better and look like a mobile app.

Please attach any previous nextjs and material ui work you have done!

Looking forward!
