It depends on if this job is for working for home or from a workplace...it depends on what the answer to that question are.
I don't know how much time you actually need per day. I have a job but i work from home so I'm doing about the same thing . Right now i do the accounting, phone calls, payrolls, emails, all calls, fix the homepage and web shop....but if its just to answer emails and filing, organizing. I would like to know anyway
