Executive assistant

I have an overwhelming schedule and would like to have a person who can help manage multiple tasks.
1) One of the tasks is to contact potential applicants and possibly do a phone screen and set up interviews. This would be a weekly task.
2) I would like to have help with managing and preparing my schedule, possibly responding to emails.
3) checking employees time and making corrections (or emailing questions about the time).
4) possibly help with Quickbooks
5) helping me to coordinate events.
6) possibly taking incoming calls and scheduling
