Change of Career?

My work from home job is ending end of this year. I have been looking for jobs with flexible hours and so far failed miserably. There is nothing close to what I have now. So, I am wondering if I can switch career at my age??!!

Selling my junk/excess on e-Bay? Was told transaction costs are high (have to pay e-Bay and Paypal) and consume lots of time for a small profit.
Be a property agent?
Be an 'investment' adviser for ourselves (with our peanut capital to go with it)?
Be a full-time homemaker and fire my maid?

Any better ideas?
