Wordpress PHP разработчик

Требуется фрилансер с опытом php, MYSQL, Javascript, Wordpress.
Необходимо добавить пару дополнительных функций в существующий вордпресс плагин и заодно показать мне как это делается.
Оплата через банковский перевод, пэйпал или наличкой.
Работа будет проходить в несколько этапов. Опалата будет за каждый выполненый этап отдельно.

Вот примерно что надо будет сделать:
1) Plugin supports booking full days vacation. Need to allow booking 0.5 days as vacation as well. I see making these fields with 1 day on screenshot editable to support 0.5 vacation.
This wil require also updating the MySQL table table structure, as there it's set to accept integers only

2) Currently the vacation approval has to be done by person with HR Manager access rights. I need it to rather be approved by Employee's direct manager (or team leader), not the HR Manager.
Thus when Employee click "Send Leave Request" the email is sent to his direct manager/team leader (the info already available in the database) instead of HR Administrator.
The Team leader, currently doesn't have access to Leave view. So to approve it, we'll need to enable "View/Approve Leave Requests" to managers and team leads, but to display there ONLY the employees that report to them directly. No others.

3) It runs on wordpress admin panel. I'll need to add there some very simple design customizations. Like adding a logo, removing some components. For example removing the Birthdays and vacations box:

4) I'll also need to modify the reporting panel. To be able to customize the report extracts to excels instead of those charts there:
