Where can I find companies that would allow me to work from home?

I think the real office careers is if you know someone in the company. I have tried so hard for so long and it appears that there are lots of people out there to scam you. My friend just got in- a friend of hers inside the company recommended her for a small job like picking up/collating/and stuffing 3000 envelopes and got paid 10 bucks an hour then she got called again two month later to make some phone calls from home. Of course, I want in but all in time. I was thinking of looking up star up companies that need part time help like bill coding, stuffing envelopes etc.
