Need to Modify Landing Page

I need to modify some features on my website landing page.
The Website has built with React.js/TypeScript.

If you have experience in TailwindCSS, it would be better.
1. menu dropdown padding fix
2. carousel(react-carousel library) speed adjustment
3. hide carousel dots.
4. footer - mobile responsive

Maximun price: 50 EUR in all.
Thank you for your time.
