Woocommerce help NEEDED, Pleeeeease

Morning, guys.

I'm in trouble here, with woocommerce. Need to finish this website today and struggling with some little things.
I'm just a curious guy with html and css, but I've tweaked what I need, until this point where I can no longer find answers.

Anyone willing to give a hand? I think that this are minor fixes/issues for people who knows about woocommerce.
Gonna insert the images with the tweaks that I need so that it can be easier for those willing to help.

Note: some of these things are related to the new woocommerce endpoints not working, I think.

For starters, the new customers don't have the chance to add a new delivery address, for some reason.


Here's the website:

So, this is the things that I couldn't figure out how to do.

Thank you so much, people.

Hope you can help me with this stuff

Cheers.

Look's like quite some PHP/Front-end work, I think it will be hard that someone is going to show up and do all this for you for no pay
Pick a budget and then post it in hire-a-freelancer section!

How much do you think?
