Adding/updating some front end responsive design on website

I have my website ready. It is pure HTML, CSS.
I am adding some new feature so I am looking for some experienced front developer who can design which looks professional.

i.e create some drop down.
create some headings like company name, user name etc.

Also I want to fix some bugs like datepicker is not showing on screen (going out of the screen) etc.

I need some "pop up" to show user weekly menu, weather alert, some offer etc.


so Basically some small design, bug issue etc.

See attached file

Front end developer should have knowledge of ftp and jira project software management.
