Improve my Wordpress DIVI site

I have an existing site: henleyriverboats.com
I am mostly happy with the site but there are a few errors and edits i don't know how to do. So I want someone experienced to make some changes. In particular, this includes making layout better on mobile.
I want to you price for:
- 20 mins phone/zoom discussion with me. i will give you login for site
- amend size of some buttons and fix some buttons not showing on mobile
- amend positioning of some pictures / images
- make 'cookie acceptance' pop-up less obtrusive
- look though all the pages and make sure they display well
2-3 hours work I imagine
Thanks
