Plenty of online workers--especially those who work from home as freelance writers or internet program junki...er, professionals--set daily goals for earning. This keeps you motivated. It sets an end time for work (you're done when you've completed $100 worth of work), which is important when you work from home. It keeps the money flowing. You can insert your own benefit as you think of reasons for working toward the $100 day.
You can choose a different number...$50, $150, $200. $100 per day, 5 days per week, is $2,000 per month. Not bad for anyone working from home.
How do you do it? Take a look at the older posts here:
I'm only listing sites that can pay off immediately, or within a week or so. Demand Studios and BrightHub both require that you apply (send resume, fill out web form), so those are contingent upon acceptance. Once accepted, you pick up assignments.
You could, for instance, in 1 day write 4 articles for Associated Content--the pay is very low there ($4-6 per article these days), but you do get residual income (ongoing ad revenue share). You could then write 2 letters for LetterRep; if accepted, that's $20. Write 3 $15 articles for Demand Studios (article fees range from $5 to $20 now). Write 2 articles for BrightHub and earn $20 (plus residuals).
That's 9 articles (each in the 400 word range), 2 letters (250 words each), and around $101-$109 for the day. If 9 articles and 2 letters sounds like a lot, it is--but it's very doable once you get going, and this is your typical work-from-home, earn $100/day scenario.
All of these sites pay via PayPal. Associated Content and Demand Studios pay weekly, while LetterRep and BrightHub pay monthly. This is why steady, constant work is important--you keep a pipeline of money coming in.
Give it a try! In the meantime, keep checking back for telecommuting job leads--I post them around 3pm EST.
