The website is very misleading at best and seems more likely a complete fraud. The "Top Pick" which states is "free" is actually 69.95 a month when you read the faded fine print that was tucked away and neatly disguised.
Grant-Funding.org appears to be a very cleaver paid advertising website and it seems likely that the "Top Pick" paid the most money to be there. it also seems likely that the only "investigation" done on these companies is checking the bank account to see if the check cleared. The PayPal donation is also cleaver to give the site an appearance of legitimacy and I'm sure that there suckers out there that "donating".
