React Dev. for Food Ordering Website Improvements

Hi! I run a small family food business, and I've built a website for online ordering. It's mostly working, but I've run into a handful of frontend issues I can't fix on my own — and I'd like someone to fix those first, then keep helping me improve and extend the site over time...
