STR - Language switcher & Book button in mobile view next to LOGO

Hi Will Myers team,

I am (Airbnb expert)property manager and i am making websites for my clients, mostly STR. I have made a six languages website in SQSP and i want the mobile menu & desktop menu as the link above? Language switcher, Also BOOK button in mobile menu next to mobile logo.Do you have something like that? or can you make me that? and if you can make it that how much will be the cost? I will tell the price to customer and he agree we will make it. Also make it as a feature, it will sell a lot, all STR that have SQSP will buy it for sure.  Also travel guides websites or tourism activities website like mine.

Thank you, regards, Manolis
