Improvements to the company website

Hello

I need someone to do some corrections to redp.pl website

Change background to a nicer one

Change main menu to more readable, symbol or names

Changing the main photo to a scrollable slider with a dialog box for editing (instructions on how to edit this field on the page)

Constant problems with wordpress editor (it does not appear) - is it possible to change it for another one , if yes I want to change it

A simple tutorial on how to edit an existing gallery

Tutorial on how to add promotional banners, which are already there , in the new editor

Set the default language to Polish - home page, and English as second language

Shop online link switches to Polish version instead of English

Make all updates.

Commissioning only by useme, on invoice for an English company (store is in England), with predetermined time of work.

Thank you:)))))
