I live walking distance to a mall. There are always cell phone and bank shops there. It wouldn't be enough to quit my job, but it adds up nicely.
If you take public transportation to work, see if there are shops along your commute and near your job.
The call center and online shops pay extremely low, but you aren't doing much.
You can also find shops that require in home visits. Those run from $15-$30.
