Virtual Assistant

Hi,
I am looking for someone to help with different tasks, it's not a daily job now but specific sporadic projects.
Some are to create databases, need to know excel, also to create presentations on powerpoint or any other tool.
Other projects involve researching for the best air flights, creating estimates and itineraries.
Some other projects are to create manuals and processes to know how to educate and follow for new people coming in.
Good use of language, compromised and responsible, but most of all a big heart human being that can relate and empathize.
