Have you looked into the Google Adsense program? What it is is you earn money online by placing ads on your website or blog. It does not cost you anything to join this program - so if you see similar solicitations and they are asking you to pay something then you will know that it is not the legitimate google adsense site.
Besides being a grant researcher and consultant, I am also a Dream Job consultant so I ask you what is it that you love to do? Could you possibly turn that into a business?
There will always be a need for consultants and I suspect your problem may be due to lack of "getting the word out" about your services. I once got a "research" client - a woman who shopped at the same supermarket as me - and I attribute this to her knowing about the kind of work that I do.
Do you have a website or blog of any kind?
Aidpage is looking for participants who want to earn money so you should go to the top of this page and hopefully find the link that you can click on to find out more about that.
I have been looking into the Paid Survey type stuff that is showing up all over the internet and I even started a blog about it however my personal opinion is not to even waste your time with these because they pay so little money!
