So you're saying that Gigster pays their subs ~$180/h? That's over $330,000 per year. So how much do they charge clients then? ~$300/h?

I doubt it. Their prices are probably similar to TopTals.

Gigster offers fixed price projects, based on $100-150/hr rate.

If you manage to get things done faster, which can happen pretty often, you end up with rate even better.

And yes, it's possible to make that amount of $ on gigster
