It's not really that easy to make huge bucks here in Hubpages. You need some investment and that is time and effort poured in this community.
You need to make more hubs (searchable and high quality ones).
The first thing you should achieve is having high amount of traffic (and that can be done when you have written very unique and useful hubs that have high value-added),
When you already have secured a daily amount of high traffic, then earning will follow. :)
As of now, I'm not earning that much too, but I'm still giving it a time. They say it takes amount a month (perhaps more) before your hubs mature -- the time when you gain ROI. Happy hubbing Chechu!
