Hi @Priscilla Z., I love that you are looking for someone local. Plus, it's great that you have the duties already listed out. Those will come in handy for posting a job opening.
I've posted jobs on indeed.com with the setting: local applicants only. Craigslist was my secondary local posting option.
Also, based on your comments: looking for someone who "loves being in front of a computer all day" and "possibly grow into a bigger position" are interesting. Hiring a college student and training them up could be an opportunity.
Florida Institute of Technology looks like it is near you and you could inquire with their career center about how to reach students with your opportunity. Their IT students could probably build automations for some of the tasks you laid out as well.
The following books have some hiring tips in general you might find interesting:
First, Break All the Rules: Hire for talent, rather than skill. Example talent: striving to grow and learn about real estate. Example skill: data mining. The book says it is better to hire the person with talent because you can teach them the skills. The book has sample talent interview questions as well.
Algorithms to Live By: Set aside x number of days to find an assistant (I'll say 30 days for this example). Refrain from hiring anyone until you have looked for 33% of the total allotted time and interviewed at least 33% of the serious applicants. Then, once you have observed what's out there, hire the next person who comes along that is the "best yet" for the job. At least, that's the most efficient way a computer would handle it ;-)
Hope this helps... please keep us posted! :-)
